Verse 20. - Their children; rather, his children; i.e. the "children of Israel."

30:18-24 We have here further intimations of the favour of God for them after the days of their calamity have expired. The proper work and office of Christ, as Mediator, is to draw near unto God, for us, as the High Priest of our profession. His own undertaking, in compliance with his Father's will, and in compassion to fallen man, engaged him. Jesus Christ was, in all this, truly wonderful. They shall be taken again into covenant with the Lord, according to the covenant made with their fathers. I will be your God: it is his good-will to us, which is the summary of that part of the covenant. The wrath of God against the wicked is very terrible, like a whirlwind. The purposes of his wrath, as well as the purposes of his love, will all be fulfilled. God will comfort all that turn to him; but those who approach him must have their hearts engaged to do it with reverence, devotion, and faith. How will they escape who neglect so great salvation?Their children also shall be as aforetime,.... In the streets of Jerusalem, numerous and free; no more in a strange land, or subject to others, Zechariah 8:5; and educated in a religious manner. Some think it refers to the times of the patriarchs before the law was given; and that the meaning is, that the law being abrogated, and they now sensible of it, shall live without it, as their forefathers did. It may be understood of the church's children in a spiritual sense; that great numbers should be born again in her as formerly, who shall profess the Christian religion, and behave according to it:

and their congregation shall be established before me; the church, consisting of them; or their church state shall be settled and confirmed, and no more be destroyed, as it formerly was:

and I will punish all that oppress them; or rather, have oppressed them; all the antichristian nations, who will now suffer the wrath of God; and after this there will be no more oppressors and persecutors of the church of God.
