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.

11. I know—I alone; not the false prophets who know nothing of My purposes, though they pretend to know.

thoughts … I think—(Isa 55:9). Glancing at the Jews who had no "thoughts of peace," but only of "evil" (misfortune), because they could not conceive how deliverance could come to them. The moral malady of man is twofold—at one time vain confidence; then, when that is disappointed, despair. So the Jews first laughed at God's threats, confident that they should speedily return; then, when cast down from that confidence, they sank in inconsolable despondency.

expected end—literally, "end and expectation," that is, an end, and that such an end as you wish for. Two nouns joined by "and," standing for a noun and adjective. So in Jer 36:27, "the roll and the words," that is, the roll of words; Ge 3:16, "sorrow and conception," that is, sorrow in conception. Compare Pr 23:18, where, as here "end" means "a happy issue."
