16 For this is what the Lord has said about the king who is seated on the seat of David's kingdom, and about all the people living in this town, your countrymen who have not gone out with you as prisoners; 17 This is what the Lord of armies has said: See, I will send on them the sword and need of food and disease, and will make them like bad figs, which are of no use for food, they are so bad. 18 I will go after them, attacking them with the sword and with need of food and with disease, and will make them a cause of fear to all the kingdoms of the earth, to be a curse and a wonder and a surprise and a name of shame among all the nations where I have sent them: 19 Because they have not given ear to my words, says the Lord, when I sent to them my servants the prophets, getting up early and sending them; but you did not give ear, says the Lord.

Commentary on Jeremiah 29:8-19
(Read Jeremiah 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.
