Jeremiah 31:17 - Matthew Poole's English Annotations on the Holy Bible

And again here, where, by end, is meant the end of the seventy years, and the words are but a repetition of the promise of the return of the Jews out of the captivity of Babylon, of which the prophet had often before assured them, and here only repeats it as an argument why they should not be immoderately afflicted; for their affliction was not endless, nor their captivity for ever; they should return again into their own land.
