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 they prophesy falsely unto you in my name,.... They pretended to have the authority of God for what they said; that their prophecies and dreams were from him, and as such they delivered them in his name; though they were false ones; that they might be the better received by the people:
I have not sent them, saith the Lord; they had no mission or commission from the Lord, no warrant or authority from him; they set up themselves; and ran without being sent; and prophesied out of their own hearts what came into their heads, the fancies of their own brain, or the delusions of Satan, under whose power and influence they were; therefore sad must be the case of a people giving heed to such seducing spirits.
