Verse 10. - Seventy years (see on Jeremiah 25:11). At Babylon; rather, for Babylon. A long period, such as seventy years, is appointed for Babylon "to enjoy" the fruits of her ambition; when this is over (comp. Genesis 15:13-16), God will pay heed to his people. Visit you. To "visit" frequently has the sense of "taking notice of," or "paying heed to" (e.g. Jeremiah 23:2). My good word. "Word," equivalent to "pro-raise;" the allusion is to Jeremiah 24:6.

29:8-19 Let men beware how they call those prophets whom they choose after their own fancies, and how they consider their fancies and dreams to be revelations from God. False prophets flatter people in their sins, because they love to be flattered; and they speak smoothly to their prophets, that their prophets may speak smoothly to them. God promises that they should return after seventy years were accomplished. By this it appears, that the seventy years of the captivity are not to be reckoned from the last captivity, but the first. It will be the bringing to pass of God's good word to them. This shall form God's purposes. We often do not know our own minds, but the Lord is never at an uncertainty. We are sometimes ready to fear that God's designs are all against us; but as to his own people, even that which seems evil, is for good. He will give them, not the expectations of their fears, or the expectations of their fancies, but the expectations of their faith; the end he has promised, which will be the best for them. When the Lord pours out an especial spirit of prayer, it is a good sign that he is coming toward us in mercy. Promises are given to quicken and encourage prayer. He never said, Seek ye me in vain. Those who remained at Jerusalem would be utterly destroyed, notwithstanding what the false prophets said to the contrary. The reason has often been given, and it justifies the eternal ruin of impenitent sinners; Because they have not hearkened to my words; I called, but they refused.For thus saith the Lord, that after seventy years be accomplished at Babylon,.... These seventy years are not to be reckoned from the last captivity under Zedekiah; nor from the precise present time; nor from the first of Jeconiah's captivity; but the fourth year of Jehoiakim, and the first of Nebuchadnezzar, when he first came up against Jerusalem; see Jeremiah 25:1;

I will visit you; in a way of mercy, by stirring up Cyrus king of Persia to grant them their liberty:

and perform my good word towards you, in causing you to return to this place; meaning the promise of return from their captivity to their own land; which was a good word of promise, a promise of good things; which was good news to them, and of which there was no doubt of its performance, since God is faithful who has promised, and is able also to perform. It was from hence, and Jeremiah 25:11; that Daniel learned the time of the captivity, and the return from it, Daniel 9:2.
