12. Now, therefore, I pray you, swear, etc. It is another manifestation of faith that she places the sons of Abraham in sure possession of the land of Canaan, founding on no other argument than her having heard that it was divinely promised to them. For she did not suppose that God was favoring lawless intruders who were forcing their way into the territories of others with unjust violence and uncurbed licentiousness, but rather concluded that they were coming into the land of Canaan, because God had assigned them the dominion of it. It cannot be believed that when they sought a passage from the Edomites and others, they said nothing as to whither they were going. Nay, those nations were acquainted with the promise which was made to Abraham, and the memory of which had been again renewed by the rejection of Esau.

Moreover, in the language of Rahab, we behold that characteristic property of faith described by the author of the Epistle to the Hebrews, when he calls it a vision, or sight of things not appearing. (Hebrews 11:1) Rahab is dwelling with her people in a fortified city: and yet she commits her life to her terrified guests, just as if they had already gained possession of the land, and had full power to save or destroy as they pleased. This voluntary surrender was, in fact, the very same as embracing the promise of God, and casting herself on his protection. She, moreover, exacts an oath, because often, in the storming of cities, the heat and tumult of the struggle shook off the remembrance of duty. In the same way she mentions the kindness she had shown to them, that gratitude might stimulate them the more to perform their promise. For although the obligation of the oath ought of itself to have been effectual, it would have been doubly base and inhumane not to show gratitude to a hostess to whom they owed deliverance. Rahab shows the kindliness of her disposition, in her anxiety about her parents and kindred. This is, indeed, natural; but many are so devoted to themselves, that children hesitate not to ransom their own lives by the death of their parents, instead of exerting courage and zeal to save them.

14. Our life for yours, etc. They imprecate death upon themselves, if they do not faithfully make it their business to save Rahab. For the interpretation adopted by some, We will pledge our lives, seems far-fetched, or too restricted, since their intention was simply to bind themselves before God. They constitute themselves, therefore, a kind of expiatory victims, if any evil befalls Rahab through their negligence. The expression, for yours, ought, doubtless, to be extended to the parents, brothers, and sisters. They therefore render their own lives liable in such a sense, that blood may be required of them, if the family of Rahab do not remain safe. And herein consists the sanctity of an oath, that though its violation may escape with impunity, so far as men are concerned, yet God having been interposed as a witness, will take account of the perfidy. In Hebrew, to do mercy and truth, is equivalent to performing the office of humanity faithfully, sincerely, and firmly.

A condition, however, is inserted, — provided Rahab do not divulge what they have said. This was inserted, not on account of distrust, as is usually expounded, but only to put Rahab more upon her guard, on her own account. The warning, therefore, was given in good faith, and flowed from pure good will: for there was a danger that Rahab might betray herself by a disclosure. In one word, they show how important it is that the matter should remain, as it were, buried, lest the woman, by inconsiderately talking of the compact, might expose herself to capital punishment. In this they show that they were sincerely anxious for her safety, since they thus early caution her against doing anything which might put it out of their power to render her a service. In further distinctly stipulating, that no one should go out of the house, or otherwise they should be held blameless, we may draw the important inference, that in making oaths soberness should be carefully attended to, that we may not profane the name of God by making futile promises on any subject.

The advice of Rahab, to turn aside into the mountain, and there remain quiet for three days, shows that there is no repugnance between faith and the precautions which provide against manifest dangers. There is no doubt that the messengers crept off to the mountain in great fear, and yet that confidence which they had conceived, from the remarkable interference of God in their behalf, directed their steps, and did not allow them to lose their presence of mind.

Some have raised the question, whether, seeing it is criminal to overleap walls, it could be lawful to get out of the city by a window? But it ought to be observed, first, that the walls of cities were not everywhere sacred, because every city had not a Romulus, who could make the overleaping a pretext for slaying his brother; ⁴¹⁴¹     This is an instance of the quiet and almost sly humor which occasionally betrays itself in Calvin’s other writings, and shows, that had it comported with the general gravity of his character, he might easily have added wit to the other weapons with which he fought the battles of the faith. In private life, when greater freedom was allowable, it appears, according to Beza’s statement, to have not infrequently contributed to the charm of his conversations. — Ed. and secondly, That law, as Cicero reminds us, was to be tempered by equity, inasmuch as he who should climb a wall for the purpose of repelling an enemy, would be more deserving of reward than punishment. The end of the law is to make the citizens secure by the protection of the walls. He, therefore, who should climb over the walls, neither from contempt nor petulance, nor fraud, nor in a tumultuous manner, but under the pressure of necessity, could not justly on that account be charged with a capital offence. Should it be objected that the thing was of bad example, I admit it; but when the object is to rescue one’s life from injury, violence, or robbery, provided it be done without offence or harm to any one, necessity excuses it. It cannot be charged upon Paul as a crime, that when in danger of his life at Damascus, he was let down by a basket, seeing he was divinely permitted to escape, without tumult, from the violence and cruelty of wicked men. ⁴²⁴²     The whole objection, as to the overleaping of walls, is so ridiculous in itself, and so very inapplicable to the circumstances of all parties at the time, that it is difficult to understand why Calvin should have condescended to notice it at all, or, at least, given himself so much trouble to refute it. If one might hazard a conjecture, it would be that some question of a similar nature had been raised in regard to the walls of Geneva, and given a local interest to a discussion which otherwise seems somewhat out of place. — Ed.
