John Gill Commentary Jeremiah 29:14

"And I will be found of you, saith Jehovah, and I will turn again your captivity, and I will gather you from all the nations, and from all the places wither I have driven you, saith Jehovah; and I will bring you again unto the place whence I caused you to be carried away captive." — Jeremiah 29:14 (ASV)

And I will be found of you, says the Lord
As he is; when his favour is shown, his presence is enjoyed, and the blessing sought for is obtained:

and I will turn away your captivity ;
this designs the captivity of Jeconiah, or of the Jews that were carried captive with him; and which had its accomplishment when the Jews returned to their own land, upon the edict of Cyrus:

and I will gather you from all the nations, and from all the places
where I have driven you, says the Lord ;
for though the greatest part might be carried to Babylon, and continue there; yet others might be removed or moved into other countries; and besides, this may respect their brethren who should come into captivity, and return with them at the end of the seventy years; for the expressions are very large and general:

and I will bring you again into the place from where I caused you to be
carried away captive ;
that is, Jerusalem, and the land of Judea; though the Vulgate Latin version renders it, ``and I will make you to return from the place to which I have caused you to go captive;'' meaning Babylon. The sense comes to the same; but the common rendering is most agreeable to the Hebrew text.
