Єремія 29:8

To make the people quiet and easy in their captivity, I. God takes them off from building upon the false foundation which their pretended prophets laid, Jer 29:8, Jer 29:9. They told them that their captivity should be short, and therefore that they must not think of taking root in Babylon, but be upon the wing to go back: "Now herein they deceive you," says God; "they prophesy a lie to you, though they prophesy in my name. But let them not deceive you, suffer not yourselves to be deluded by them." As long as we have the word of truth to try the spirits by it is our own fault if we be deceived; for by it we may be undeceived. Hearken not to your dreams, which you cause to be dreamed. He means either the dreams or fancies which the people pleased themselves with, and with which they filled their own heads (by thinking and speaking of nothing else but a speedy enlargement when they were awake they caused themselves to dream of it when they were asleep, and then took that for a good omen, and with it strengthened themselves in their vain expectations), or the dreams which the prophets dreamed and grounded their prophecies upon. God tells the people, They are your dreams, because they pleased them, were the dreams that they desired and wished for. They caused them to be dreamed; for they hearkened to them, and encouraged the prophets to put such deceits upon them, desiring them to prophesy nothing but smooth things, Isa 30:10. They were dreams of their own bespeaking. False prophets would not flatter people in their sins, but that they love to be flattered, and speak smoothly to their prophets that their prophets may speak smoothly to them. II. He gives them a good foundation to build their hopes upon. We would not persuade people to pull down the house they have built upon…
