10. And Jehovah added to speak to Ahaz. ¹⁰⁸¹⁰⁸     Moreover, the LORD spake again to Ahaz. — Eng. Ver. As the Lord knew that King Ahaz was so wicked as not to believe the promise, so he enjoins Isaiah to confirm him by adding a sign; for when God sees that his promises do not satisfy us, he makes additions to them suitable to our weakness; so that we not only hear him speak, but likewise behold his hand displayed, and thus are confirmed by an evident proof of the fact. Here we ought carefully to observe the use of signs, that is, the reason why God performs miracles, namely, to confirm us in the belief of his word; for when we see his power, if we have any hesitation about what he says to us, our doubt is removed by beholding the thing itself; for miracles added to the word are seals.

11. Either in the deep. I understand it simply to mean Either above or below. He allows him an unrestricted choice of a miracle, to demand either what belongs to earth or what belongs to heaven. But perhaps in the word deep there is something still more emphatic; as if he had said, “It belongs to you to choose. God will immediately show that his dominion is higher than this world, and that it likewise extends to all depths, so that at his pleasure he can raise the dead from their graves.” It was undoubtedly astonishing forbearance towards this wicked king and people of God, that not only did he patiently bear their distrust for a time, but so graciously condescended to them that he was willing to give them any pledge of his power which they chose. Yet he had in his eye not unbelievers only, but he intended likewise to provide for the benefit of the weak, in whom there was a seed of godliness; that they might be fully convinced that Isaiah did not speak at random, for he could easily give a proof of the power of God in confirmation of what he had said.

The same goodness of God is now also displayed towards men, to whom he exercises such forbearance, when he might justly have been offended at them; for how shockingly do they insult God, when they doubt his truth? What do you leave to God, if you take that from him? And whatever may be our doubts, not only does he pardon us, but even aids our distrust, and not only by his word, but by adding miracles; and he exhibits them not only to believers, but also to the ungodly, which we may behold in this king. And if he was at that time so kind to strangers, what ought not his own people to expect from him?

12. And Ahaz said. By a plausible excuse he refuses the sign which the Lord offered to him. That excuse is, that he is unwilling to tempt the LORD; for he pretends to believe the words of the Prophet, and to ask nothing more from God than his word. Ungodliness is certainly detestable in the sight of God, and in like manner God unquestionably sets a high value on faith. Accordingly, if a man rely on his word alone, and disregard everything else, it might be thought that he deserves the highest praise; for there can be no greater perfection than to yield full submission and obedience to God.

But a question arises. Do we tempt God, when we accept what he offers to us? Certainly not. Ahaz therefore speaks falsehood, when he pretends that he refuses the sign, because he is unwilling to tempt God; for there can be nothing fitter or more excellent than to obey God, and indeed it is the highest virtue to ask nothing beyond the word of God; and yet if God choose to add anything to his word, it ought not to be regarded as a virtue to reject this addition as superfluous. It is no small insult offered to God, when his goodness is despised in such a manner as if his proceedings towards us were of no advantage, and as if he did not know what it is that we chiefly need. We know that faith is chiefly commended on this ground, that it maintains obedience to him; but when we wish to be too wise, and despise anything that belongs to God, we are undoubtedly abominable before God, whatever excuse we may plead before men. While we believe the word of God, we ought not to despise the aids which he has been pleased to add for the purpose of strengthening our faith.

For instance, the Lord offers to us in the gospel everything necessary for salvation; for when he brings us into a state of fellowship with Christ, the sum of all blessings is truly contained in him. What then is the use of Baptism and the Lord’s Supper? Must they be regarded as superfluous? Not at all; for any one who shall actually, and without flattery, acknowledge his weakness, of which all from the least to the greatest are conscious, will gladly avail himself of those aids for his support. We ought indeed to grieve and lament, that the sacred truth of God needs assistance on account of the defect of our flesh; but since we cannot all at once remove this defect, any one who, according to his capacity shall believe the word, will immediately render full obedience to God. Let us therefore learn to embrace the signs along with the word, since it is not in the power of man to separate them.

When Ahaz refuses the sign offered to him, by doing so he displays both his obstinacy and his ingratitude; for he despises what God had offered for the highest advantage. Hence also it is evident how far we ought to ask signs, namely, when God offers them to us; and therefore he who shall reject them when offered, must also reject the grace of God. In like manner fanatics of the present day disregard Baptism and the Lord’s Supper, and consider them to be childish elements. They cannot do this without at the same time rejecting the whole gospel; for we must not separate those things which the Lord has commanded us to join.

But a question may be asked, Is it not sometimes lawful to ask signs from the Lord? For we have an instance of this in Gideon, who wished to have his calling confirmed by some sign. (Judges 6:17.) The Lord granted his prayer, and did not disapprove of such a desire. I answer, though Gideon was not commanded by God to ask a sign, yet he did so, not at his own suggestion, but by an operation of the Holy Spirit. We must not abuse his example, therefore, so that each of us may freely allow himself that liberty; for so great is the forwardness of men that they do not hesitate to ask innumerable signs from God without any proper reason. Such effrontery ought therefore to be restrained, that we may be satisfied with those signs which the Lord offers to us.

Now, there are two kinds of signs; for some are extraordinary, and may be called supernatural; such as that which the Prophet will immediately add, and that which, we shall afterwards see, was offered to Hezekiah. (Isaiah 38:7.) Some are ordinary, and in daily use among believers, such as Baptism and the Lord’s Supper, which contain no miracle, or at least may be perceived by the eye or by some of the senses. What the Lord miraculously performs by his Spirit is unseen, but in those which are extraordinary the miracle itself is seen. Such is also the end and use of all signs; for as Gideon was confirmed by an astonishing miracle, so we are confirmed by Baptism and the Lord’s Supper, though our eyes behold no miracle.

13. And he said, Hear now, O house of David. Under the pretense of honor to exclude the power of God, which would maintain the truth of the promise, was intolerable wickedness; and therefore the Prophet kindles into warmer indignation, and more sharply rebukes wicked hypocrites. Though it would have been honorable to them to be reckoned the descendants of David, provided that they imitated his piety, yet it is rather for the sake of reproach that he calls them the posterity or family of David. It was indeed no small aggravation of the baseness, that the grace of God was rejected by that family from which the salvation of the whole world would proceed. Grievous disgrace must have been brought on them, by naming their ancestry, from which they had so basely and shamefully degenerated.

This order ought to be carefully observed; for we ought not to begin with severe reproof, but with doctrine, that men may be gently drawn by it. When plain and simple doctrine is not sufficient, proofs must be added. But if even this method produce no good effect, it then becomes necessary to employ greater vehemence. Such is the manner in which we hear Isaiah thundering on the present occasion. After having exhibited to the king both doctrine and signs, he now resorts to the last remedy, and sharply and severely reproves an obstinate man; and not him only, but the whole royal family which was guilty of the same kind of impiety.

Is it a small thing for you to weary men? He makes a comparison between God and men; not that it is possible to make an actual separation between God and the prophets and holy teachers of whom he speaks, who are nothing else than God’s instruments, and make common cause with him, when they discharge their duty; for of them the Lord testifies,

He who despiseth you despiseth me.
He who heareth you heareth me. (Luke 10:16.)

The Prophet therefore adapts his discourse to the impiety of Ahaz, and of those who resembled him; for they thought that they had to deal with men. Those very words were undoubtedly spoken in ancient times which we hear at the present day from the mouths of the ungodly: “Are they not men that speak to us?” And thus they endeavor to disparage the doctrine which comes from God. As it was customary at that time for irreligious despisers of doctrine to use the same kind of language, the Prophet, by way of admission, says that those who performed the sacred office of teaching the word were men. “Be it so. You tell me that I am a mortal man. That is the light in which you view the prophets of God. But is it a small thing to weary us, if you do not also weary God? Now, you despise God, by rejecting the sign of his astonishing power which he was willing to give to you. In vain therefore do you boast that you do not despise him, and that you have to do with men, and not with God.” This then is the reason why the Prophet was so greatly enraged. Hence we see more clearly what I mentioned a little before, that the proper season for giving reproofs is, when we have attempted everything that God enjoined, and have neglected no part of our duty. We ought then to break out with greater vehemence, and to expose the ungodliness which lurked under those cloaks of hypocrisy.

My God. He formerly said, Ask a sign for thee from the Lord thy God; for at that time his obstinacy and rebellion had not been manifestly proved. But now he claims it as peculiar to himself; for Ahaz, and those who resembled him, had no right to boast of the name of God. He therefore intimates that God is on his side, and is not on the side of those hypocrites: and in this way he testifies his confidence; for he shows how conscientiously he promised deliverance to the king; as if he had said, that he did not come but when God sent him, and that he said nothing but what he was commanded to say. With the same boldness ought all ministers to be endued, not only so as to profess it, but to have it deeply rooted in their hearts. The false prophets also boast of it loudly, but it is empty and unmeaning talk, or a blind confidence arising from rashness.

14. Therefore the Lord himself shall give you a sign. Ahaz had already refused the sign which the Lord offered to him, when the Prophet remonstrated against his rebellion and ingratitude; yet the Prophet declares that this will not prevent God from giving the sign which he had promised and appointed for the Jews. But what sign?

Behold, a virgin shall conceive. This passage is obscure; but the blame lies partly on the Jews, who, by much cavilling, have labored, as far as lay in their power, to pervert the true exposition. They are hard pressed by this passage; for it contains an illustrious prediction concerning the Messiah, who is here called Immanuel; and therefore they have labored, by all possible means, to torture the Prophet’s meaning to another sense. Some allege that the person here mentioned is Hezekiah; and others, that it is the son of Isaiah.

Those who apply this passage to Hezekiah are excessively impudent; for he must have been a full-grown man when Jerusalem was besieged. Thus they show that they are grossly ignorant of history. But it is a just reward of their malice, that God hath blinded them in such a manner as to be deprived of all judgment. This happens in the present day to the papists, who often expose themselves to ridicule by their mad eagerness to pervert the Scriptures.

As to those who think that it was Isaiah’s son, it is an utterly frivolous conjecture; for we do not read that a deliverer would be raised up from the seed of Isaiah, who should be called Immanuel; for this title is far too illustrious to admit of being applied to any man.

Others think, or, at least, (being unwilling to contend with the Jews more than was necessary,) admit that the Prophet spoke of some child who was born at that time, by whom, as by an obscure picture, Christ was foreshadowed. But they produce no strong arguments, and do not show who that child was, or bring forward any proofs. Now, it is certain, as we have already said, that this name Immanuel could not be literally applied to a mere man; and, therefore, there can be no doubt that the Prophet referred to Christ.

But all writers, both Greek and Latin, are too much at their ease in handling this passage; for, as if there were no difficulty in it, they merely assert that Christ is here promised from the Virgin Mary. Now, there is no small difficulty in the objection which the Jews bring against us, that Christ is here mentioned without any sufficient reason; for thus they argue, and demand that the scope of the passage be examined: “Jerusalem was besieged. The Prophet was about to give them a sign of deliverance. Why should he promise the Messiah, who was to be born five hundred years afterwards?” By this argument they think that they have gained the victory, because the promise concerning Christ had nothing to do with assuring Ahaz of the deliverance of Jerusalem. And then they boast as if they had gained the day, chiefly because scarcely any one replies to them. That is the reason why I said that commentators have been too much at their ease in this matter; for it is of no small importance to show why the Redeemer is here mentioned.

Now, the matter stands thus. King Ahaz having rejected the sign which God had offered to him, the Prophet reminds him of the foundation of the covenant, which even the ungodly did not venture openly to reject. The Messiah must be born; and this was expected by all, because the salvation of the whole nation depended on it. The Prophet, therefore, after having expressed his indignation against the king, again argues in this manner: “By rejecting the promise, thou wouldest endeavor to overturn the decree of God; but it shall remain inviolable, and thy treachery and ingratitude will not hinder God from being, continually the Deliverer of his people; for he will at length raise up his Messiah.”

To make these things more plain, we must attend to the custom of the Prophets, who, in establishing special promises, lay down this as the foundation, that God will send a Redeemer. On this general foundation God everywhere builds all the special promises which he makes to his people; and certainly every one who expects aid and assistance from him must be convinced of his fatherly love. And how could he be reconciled to us but through Christ, in whom he has freely adopted the elect, and continues to pardon them to the end? Hence comes that saying of Paul, that

all the promises of God in Christ are Yea and Amen.
(2 Corinthians 1:20.)

Whenever, therefore, God assisted his ancient people, he at the same time reconciled them to himself through Christ; and accordingly, whenever famine, pestilence, and war are mentioned, in order to hold out a hope of deliverance, he places the Messiah before their eyes. This being exceedingly clear, the Jews have no right to make a noise, as if the Prophet made an unseasonable transition to a very remote subject. For on what did the deliverance of Jerusalem depend, but on the manifestation of Christ? This was, indeed, the only foundation on which the salvation of the Church always rested.

Most appropriately, therefore, did Isaiah say, “True, thou dost not believe the promises of God, but yet God will fulfill them; for he will at length send his Christ, for whose sake he determines to preserve this city. Though thou art unworthy, yet God will have regard to his own honor.” King Ahaz is therefore deprived of that sign which he formerly rejected, and loses the benefit of which he proved himself to be unworthy; but still God’s inviolable promise is still held out to him. This is plainly enough intimated by the particle לכן, (lachen,) therefore; that is, because thou disdainest that particular sign which God offered to thee, הוא, (hu,) He, that is, God himself, who was so gracious as to offer it freely to thee, he whom thou weariest will not fail to hold out a sign. When I say that the coming of Christ is promised to Ahaz, I do not mean that God includes him among the chosen people, to whom he had appointed his Son to be the Author of salvation; but because the discourse is directed to the whole body of the people.

Will give you a sign. The word לכם, (lachem,) to you, is interpreted by some as meaning to your children; but this is forced. So far as relates to the persons addressed, the Prophet leaves the wicked king and looks to the nation, so far as it had been adopted by God. He will therefore give, not to thee a wicked king, and to those who are like thee, but to you whom he has adopted; for the covenant which he made with Abraham continues to be firm and inviolable. And the Lord always has some remnant to whom the advantage of the covenant belongs; though the rulers and governors of his people may be hypocrites.

Behold, a virgin shall conceive. The word Behold is used emphatically, to denote the greatness of the event; for this is the manner in which the Spirit usually speaks of great and remarkable events, in order to elevate the minds of men. The Prophet, therefore, enjoins his hearers to be attentive, and to consider this extraordinary work of God; as if he had said, “Be not slothful, but consider this singular grace of God, which ought of itself to have drawn your attention, but is concealed from you on account of your stupidity.”

Although the word עלמה, (gnalmah,) a virgin, is derived from עלם, (gnalam,) which signifies to hide, because the shame and modesty of virgins does not allow them to appear in public; yet as the Jews dispute much about that word, and assert that it does not signify virgin, because Solomon used it to denote a young woman who was betrothed, it is unnecessary to contend about the word. Though we should admit what they say, that עלמה (gnalmah) sometimes denotes a young woman, and that the name refers, as they would have it, to the age, (yet it is frequently used in Scripture when the subject relates to a virgin,) the nature of the case sufficiently refutes all their slanders. For what wonderful thing did the Prophet say, if he spoke of a young woman who conceived through intercourse with a man? It would certainly have been absurd to hold out this as a sign or a miracle. Let us suppose that it denotes a young woman who should become pregnant in the ordinary course of nature; ¹⁰⁹¹⁰⁹     Quae ex coitu viri gravida esset futura. everybody sees that it would have been silly and contemptible for the Prophet, after having said that he was about to speak of something strange and uncommon, to add, A young woman shall conceive. It is, therefore, plain enough that he speaks of a virgin who should conceive, not by the ordinary course of nature, but by the gracious influence of the Holy Spirit. And this is the mystery which Paul extols in lofty terms, that

God was manifested in the flesh. (1 Timothy 3:16.)

And shall call. The Hebrew verb is in the feminine gender, She shall call; for as to those who read it in the masculine gender, I know not on what they found their opinion. The copies which we use certainly do not differ. If you apply it to the mother, it certainly expresses something different from the ordinary custom. We know that to the father is always assigned the right of giving a name to a child; for it is a sign of the power and authority of fathers over children; and the same authority does not belong to women. But here it is conveyed to the mother; and therefore it follows that he is conceived by the mother in such a manner as not to have a father on earth; otherwise the Prophet would pervert the ordinary custom of Scripture, which ascribes this office to men only. Yet it ought to be observed that the name was not given to Christ at the suggestion of his mother, and in such a case it would have had no weight; but the Prophet means that, in publishing the name, the virgin will occupy the place of a herald, because there will be no earthly father to perform that office.

Immanuel. This name was unquestionably bestowed on Christ on account of the actual fact; for the only-begotten Son of God clothed himself with our flesh, and united himself to us by partaking of our nature. He is, therefore, called God with us, or united to us; which cannot apply to a man who is not God. The Jews in their sophistry tell us that this name was given to Hezekiah; because by the hand of Hezekiah God delivered his people; and they add, “He who is the servant of God represents his person.” But neither Moses nor Joshua, who were deliverers of the nation, were so denominated; and therefore this Immanuel is preferred to Moses and Joshua, and all the others; for by this name he excels all that ever were before, and all that shall come after him; and it is a title expressive of some extraordinary excellence and authority which he possesses above others. It is therefore evident that it denotes not only the power of God, such as he usually displays by his servant, but a union of person, by which Christ became God-man. Hence it is also evident that Isaiah here relates no common event, but points out that unparalleled mystery which the Jews labor in vain to conceal.
