Charles Ellicott Commentary Jeremiah 14:1

"The word of Jehovah that came to Jeremiah concerning the drought." — Jeremiah 14:1 (ASV)

Concerning the drought. —Literally, on the report or news of the drought. This is clearly the opening of a new discourse, which continues to Jeremiah 17:18; but as no special calamity of this kind is mentioned in the historical account of Jeremiah’s life, its date cannot be fixed with certainty. As Jeremiah 15:15 implies that he had already suffered scorn or persecution for his prophetic work, we may reasonably assume some period not earlier than the reign of Jehoiakim.
