Isaiah 66:12

For thus saith the LORD, Behold, I will extend peace to her like a river, and the glory of the Gentiles like a flowing stream: then shall ye suck, ye shall be borne upon her sides, and be dandled upon her knees.

For thus saith the Lord, behold, I will extend peace to her like a river,.... As the river Euphrates, so the Targum; or as the Nile, which overflowed Egypt, and made it fruitful; or as any flowing river, large and spreading, continuing to flow, and brings blessings with it where it comes; and so denotes the abundance of this peace, the perpetuity of it, and its blessed effects. This respects not the first times of the Gospel; for though Christ the peacemaker came and made peace by his blood, and went and preached peace to Jews and Gentiles, and many enjoyed spiritual peace in believing, flowing from his blood and righteousness, yet there was very little outward peace to the churches of Christ; and when at any time had, did not last long: but, in the latter day, not only spiritual peace, which passeth all understanding, and joy unspeakable and full of glory, will be extended unto and possessed by the saints; but outward peace in great abundance, and of lasting continuance, with all kind of prosperity, temporal and spiritual, Psalms 72:7: and the glory of the Gentiles like a flowing stream; like the Nile, that overflows; meaning either the vast number of converts, from among the Gentiles, that shall flow into the church, and especially many of their great men, princes, nobles, even kings and queens, who shall be nursing fathers and nursing mothers to her; see Isaiah 60:3, or their riches, which are the honour and glory they shall bring with them to the church in great abundance, and shall cheerfully and freely expend them in the service and worship of God, Isaiah 60:6 so Kimchi interprets it of their wealth and substance:

then shall ye suck; the milk of the Gentiles, and the breasts of kings; that is, partake of their good things, Isaiah 60:16 or the church's breasts of consolation, the sincere milk of the word and ordinances,

Isaiah 60:11, this is spoken to the friends of Zion, and lovers of Jerusalem, newly converted persons, Isaiah 66:10:

ye shall be borne upon her sides, or "side" {y}; children being carried by parents or nurses on one side of them in their arms; it denotes the affectionate care and regard the church has to young converts, who are said to be nursed at her side, Isaiah 60:4 she supporting and supplying them with everything in her power, by means of the word and ordinances:

and be dandled upon her knees: as darling children are, who are taken into the lap, and played with, and are the delight, the exceeding great delight, of their parents; and where they delight to be, as the word {z} used signifies. All shows that young converts are and should be made much of, and tenderly used; the day of small things should not be despised, or the bruised reed broken, or the smoking flax quenched; but these lambs should be gathered into the arms, and carried in the bosom, like sucking children.
