Jeremiah 29:14 - Matthew Poole's English Annotations on the Holy Bible

This verse containeth no more than was said before, only it is repeated in a little different phrase, for the further confirmation of their faith, and the promise is a little enlarged. God saith he will be found of them, that is, he will answer them. It is expressed in this nation to correspond with the term seeking, by which prayer is expressed, and to let us know that those that will have God's favour must find it; which implieth a seeking and inquiry after it. The promise, which before mentioned only their return from Babylon, is enlarged, and made here to extend to all places whither they were driven; for though the body of the people were carried to Babylon, yet it is more than probable that many of them shifted for themselves into other countries, and were in exile, but not in captivity. Cyrus's proclamation, 2 Chronicles 36:22,23, extended to his whole empire.
