4. I will make mention of Rahab and Babel. The name of Rahab is put for Egypt in many other parts of Scripture; and this signification is very suitable to the present passage, the object of which is to portray the magnificent amplitude of the Church, which as yet was only matter of hope. It is therefore said that those who formerly were deadly enemies, or entire strangers, shall not only become familiar friends, but shall also be ingrafted into one body, that they may be accounted citizens of Jerusalem. In the first clause it is said, I will make mention of Egypt and Babylon among my household. In the second, it is added, that the Philistines, Tyrians, and Ethiopians, who hitherto had been so much at variance with the people of God, shall now be brought into as cordial harmony with them as if they were Jews by birth. What a glorious distinction of the Church, that even those who held her in contempt shall come flocking to her from every quarter, and that those who desired to see her completely cut up and destroyed, shall consider it the highest honor to have a place among the number of her citizens, and to be accounted such! All of them shall voluntarily renounce their own countries in which they had before proudly boasted. Wherever they may have been born, whether in Palestine, or Ethiopia, or Tyre, they shall profess themselves citizens of the holy city.

The Hebrew doctors explain this passage as meaning, that there shall spring from other nations very few who shall excel either in mental endowment or in virtuous attainment, but that in Israel such persons will be very numerous. Scarcely, say they, will there be found among the Tyrians, the Egyptians, the Ethiopians, and other nations, a man to each of them worthy of praise; so that if such an one be found among them, he may be pointed at with the finger, on account of his rarity; but in Zion man and man shall be born; ⁴ that is to say, the number of such men among the Jews shall be great. Christian doctors are almost unanimous in referring these words to Christ, and think that the cause is here assigned why those who hitherto were strangers, and even mortal enemies to each other, are now to be numbered among the citizens of Jerusalem, namely, because Christ shall be born there, ⁵ whose office it is to gather together into the unity of faith and hope of eternal life, men who were scattered like members torn from the body. The first of these interpretations being altogether forced, needs no refutation. Moreover, it is very evident that the Jews, actuated by a foolish ambition, wrest this passage as it were purposely. The exposition of the Christian doctors is, at first sight, plausible from its ingenuity; but it is destitute of solidity. The words clearly imply, that whatever nation men may belong to, they shall willingly renounce their own country, to be enrolled in the Register of the chosen people. When it is said, that they are born there, this does not mean that they are natives of the country, and have been brought up in it from their birth, but that they are its citizens. What is added afterwards, The Most High himself will establish her, may, with equal propriety, be translated, will order her; it being the work of God specially to govern his Church by his word.

5. And it shall be said of Zion, Man and man is born in her. It is asserted, in the 4th verse, That new citizens shall be gathered into the Church of God from different parts of the world; and here the same subject is prosecuted. Another figure is however employed, which is, that strangers by birth shall be accounted among the holy people, just as if they were descended from Abraham. It had been stated in the preceding verse, that the Chaldeans and Egyptians would be added to the household of the Church; and that the Ethiopians, Philistines, and Tyrians, would be enrolled among her children. Now, it is added, by way of confirmation, that the number of the new progeny shall be exceeding great, so that the city which had been for a time uninhabited, and afterwards only half filled with a few people, shall be crowded with a vast population. The prophet Isaiah describes more at length what is here promised, in a few words,

"Sing, O barren, thou that didst not bear; break forth into singing, and cry aloud, thou that didst not travail with child: for more are the children of the desolate than the children of the married wife, saith the Lord. Enlarge the place of thy tent, and let them stretch forth the curtains of thine habitations: spare not, lengthen thy cords, and strengthen thy stakes: for thou shalt break forth on the right hand and on the left; and thy seed shall inherit the Gentiles, and make the desolate cities to be inhabited." (Isaiah 54:1)

Also,

"Lift up thine eyes round about, and see; all they gather themselves together, they come to thee: thy sons shall come from far, and thy daughters shall be nursed at thy side."
(Isaiah 60:4)

And, in the 44th chapter, at the 5th verse, we meet with almost the same language as in the passage before us, or at least what comes very near to it: "One shall say, I am the Lord's; and another shall call himself by the name of Jacob; and another shall subscribe with his hand unto the Lord, and surname himself by the name of Israel." Nor is the word born inappropriately employed to express the fact, that the Egyptians, Chaldeans, and such like, shall be of the flock of God's people. Although Zion was not the place of their natural birth, but they were to be grafted into the body of the holy people by adoption; yet as the way by which we enter into the Church is a second birth, this form of expression is used with great propriety. The condition upon which Christ espouses the faithful to himself is, that they should forget their own people and their father's house, (Psalm 45:11,) and that, being formed into new creatures, and born again of incorruptible seed, they should begin to be the children of God as well as of the Church, (Galatians 4:19.) And the ministry of the Church, and it alone, is undoubtedly the means by which we are born again to a heavenly life. By the way, we should remember the difference which the Apostle sets forth as subsisting between the earthly Jerusalem, -- which, being herself a bondwoman, brings forth children also in bondage, -- and the heavenly Jerusalem, which brings forth free children by the instrumentality of the Gospel.

In the second part of the verse, there is expressed the stability and enduring character of Zion. It often happens, that in proportion to the rapidity with which cities rise to distinguished eminence, is the shortness of the continuance of their prosperity. That it may not be thought that the prosperity of the Church is of such a perishable and transitory nature, it is declared, that the Most High himself will establish her. It is not surprising, as if it had been said, to find other cities shaken, and subject from time to time to a variety of vicissitudes; for they are carried round with the world in its revolutions, and do not enjoy everlasting defenders. But it is the very reverse with respect to the new Jerusalem, which, being founded upon the power of God, will continue even when heaven and earth shall fall into ruins.

6. The Lord will recount, when he writeth the peoples. The meaning is, that Zion will acquire such renown as to excite all men with the greatest earnestness to desire to be admitted into the number and rank of her citizens. It is a highly honorable condition which is spoken of, the language implying, that when God shall take a census of the people on whom he will be graciously pleased to confer the highest honor, he will write them as belonging to Zion, rather than to Babylon or any other cities; for to be one of the common people among the citizens of Zion, will be a greater distinction than to be invested with the highest rank anywhere else. We are, at the same time, taught that the cause to which we are to trace the sudden elevation of these aliens to so great honor, is the favor of God. Those who are the bondslaves of Satan and of sin will assuredly never be able to obtain, by any efforts of their own, the right of citizenship in the heavenly Jerusalem. It is the Lord's peculiar work to divide people into their respective ranks, distinguishing one from another, as seemeth good to him, all men being on a level by nature. This passage is to be understood as referring to effectual calling. God, it is true, wrote the names of his children in the Book of Life before the creation of the world; but he enrols them in the catalogue of his saints, only when, having regenerated them by the Spirit of adoption, he impresses his own mark upon them.
