Albert Barnes Commentary Jeremiah 30:10-11

"Therefore fear thou not, O Jacob my servant, saith Jehovah; neither be dismayed, O Israel: for, lo, I will save thee from afar, and thy seed from the land of their captivity; and Jacob shall return, and shall be quiet and at ease, and none shall make him afraid. For I am with thee, saith Jehovah, to save thee: for I will make a full end of all the nations whither I have scattered thee, but I will not make a full end of thee; but I will correct thee in measure, and will in no wise leave thee unpunished." — Jeremiah 30:10-11 (ASV)

These two verses are considered by some very similar in style to the last 27 chapters of Isaiah. The contrast, however, between the full end made with the pagan, and the certainty that Israel shall never so perish, is one of Jeremiah’s most common topics (Jeremiah 30:11).
