Charles Ellicott Commentary Jeremiah 46:27-28

"But fear not thou, O Jacob my servant, 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. Fear not thou, O Jacob my servant, saith Jehovah; for I am with thee: for I will make a full end of all the nations whither I have driven 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 46:27-28 (ASV)

Fear not thou, O my servant Jacob ... —The words that follow are found also in Jeremiah 30:10-11, and have been commented on there, and were either inserted here by the prophet himself, or by some later editor of his writings, as an appropriate conclusion, contrasting the care of Jehovah for His people with the sentence upon the power in which they were trusting for protection. Why should they insist, as in Jeremiah 43:7, on placing themselves in a position which would involve them in the destruction which the prophet thus foretells?

The words, it may be noticed, are a manifest echo of the words of Isaiah (Isaiah 41:13; Isaiah 43:5). Such a consolation was, we may well believe, needed by the people when they saw the armies of Nebuchadnezzar laying waste the country in whose protection they had trusted, and where they had hoped to find a home. Better things, they are told, were in store for them, even a return to the land of their fathers.
