15. Because--referring not to the preceding words, but to Jer 29:10, 11, "Jehovah saith this to you" (that is, the prophecy of the continuance of the captivity seventy years), "because ye have said, The Lord hath raised us up prophets in Babylon," namely, foretelling our speedy deliverance (this their prophecy is supposed, not expressed; accordingly, Jer 29:16-19 contradict this false hope again, Jer 29:8, 9, 21). He, in this fifteenth verse, turns his address from the godly (Jer 29:12-14) to the ungodly listeners, to false prophets.
