Charles Ellicott Commentary Jeremiah 34:1

"The word which came unto Jeremiah from Jehovah, when Nebuchadnezzar king of Babylon, and all his army, and all the kingdoms of the earth that were under his dominion, and all the peoples, were fighting against Jerusalem, and against all the cities thereof, saying:" — Jeremiah 34:1 (ASV)

When Nebuchadnezzar king of Babylon ... —The prophecy that follows is probably a fuller statement of that in Jeremiah 32:3-4, and delivered shortly before it, being referred to there as the cause of his imprisonment. In the form of the name Nebuchadnezzar (n instead of r, as in Jeremiah 24:1; Jeremiah 25:1), we may probably trace the hand of a later transcriber. The same hand is, perhaps, traceable in the accumulation of substantives after the manner of Daniel 3:7; Daniel 5:19.
