Charles Ellicott Commentary Jeremiah 29:11

"For I know the thoughts that I think toward you, saith Jehovah, thoughts of peace, and not of evil, to give you hope in your latter end." — Jeremiah 29:11 (ASV)

For I know the thoughts ... —The word used for “saith the Lord” implies that the gracious promise came to the prophet’s soul as an oracle from heaven. In the “thoughts” of God there is, perhaps, a reference to what had been said before of the Babylonian exiles in Jeremiah 24:6.

To give you an expected end. —Better, to give you a future (what is to come) and a hope. This is the literal rendering of the words, and it is far more expressive than that of the English version. An “expected end” may be one from which we shrink in fear or dislike. Each word, in the amended translation, has its full meaning. The “future” tells them that their history as a people is not yet over; the “hope” that there is a better time in store for them. To wait for that future, instead of trusting in delusive assurances of immediate release, was the true wisdom of the exiles.
