I will make mention of Rahab,.... Not of Rahab the harlot, as Jerom and others of the ancients interpret it; for the letters of both words are not the same in Hebrew; though mention is made of her in the Gospel, and Gospel times, in the genealogy of Christ, and by two of the apostles, Mt 1:5, but of Egypt; and so the Targum interprets it, which is so called, as it is in Ps 89:10 either from the pride of its inhabitants, the word having in it the sense of pride and haughtiness, and these being naturally proud and haughty, as Philo the Jew observes; or from some city of this name in it; or rather this respects that part of Egypt called Delta, which was in the form of a pear; which "raab", or "rib", in the Egyptian language, signifies; in the midst of which was the city of Athribis of Ptolemy , which has its name from hence, and signifies the heart of a pear; and still this part of the country is called Errifia, as Leo Africanus relates, and is here put for the whole country: the passage respects the conversion of it, and are the words of God foretelling it, and of which mention is made in Isa 19:18 and had its accomplishment, at least in part, on the day of Pentecost, Ac 2:10 and will be further accomplished in the latter day, when the people that now inhabit that country shall be converted, which will be when the kingdoms of this world become Christ's: and Babylon; the country of the Assyrians and Chaldeans, of which Babylon was the metropolis: mention is made of the conversion of these in Isa 19:24 and which also was fulfilled, in part, on the day of Pentecost, Ac 2:9 and in Babylon there was a church, in the times of the Apostle Peter, 1Pe 5:13 these the Lord promises that he would make mention of:to them that know me; says he, that so they might expect their conversion, and take notice of them, and receive them, when converted;or among them that know me ; that is, I will make mention of them, as such that know me, and belong to that number; even such that love the Lord, believe in him, own and confess him, and yield obedience to him, and whom he takes into communion and fellowship with himself, and makes his friends, familiars, and acquaintance:behold Philistia, and Tyre, with Ethiopia; where also will be many converts, regenerate persons, and such as know the Lord; of which there has been a partial accomplishment already; of Philistia, see Ac 8:40, for Azotus, or Ashdod, was a city of the Philistines; and of Tyre, see Ps 45:12 and of Ethiopia, and its conversion, mention is made in Ps 68:31, and the Ethiopian eunuch is one instance of it, Ac 8:27 of all which there will be abundance of instances in the latter day; and thus, as the church is commended from her foundation, from the superlative love the Lord bears to her, and the glorious things spoken of her; so from the number of her converts in different nations, in which her glory in Gospel times would greatly lie; see Isa 49:18,this man was born there; not any particular man; any single individual, famous for piety, wisdom, wealth, or power; as if it suggested that now and then such a person might be born in the above countries; whereas in Zion there were frequently many such persons born: nor is it to be understood of the Messiah, that should come out of Zion, as if that was the reason why multitudes from the above places should flock thither, because of the birth of this illustrious Person: the Targum understands it of a great personage, a king; and paraphrases it,"a king is educated there;''but it designs many persons in each of those countries that should be born again, of water, and of the Spirit, of the incorruptible seed of grace, by the ministry of the word; who, because they should be regenerated by means of the Gospel preached in Zion, therefore are said to be born there; and besides, being born again, they are admitted members of Zion, and to all the privileges of Zion, as true born Israelites; and are brought up there, are nourished with the sincere milk of the word, and nursed with the breasts of Gospel ordinances there administered; and so Zion, or Jerusalem, the Gospel church, is truly the mother of them all, Ga 4:26.
