Neither shall Pharaoh with his mighty army and great company make for him in the war, by casting up mounts, and building forts, to cut off many persons:
Pharaoh - Pharaoh-hophra (Jeremiah 37:7; Jeremiah 44:30), the successor of Necho (2 Kings 23:29).
Neither shall Pharaoh with his mighty army ... make for him - literally, 'effect (anything) with him,' i:e., be of any avail to Zedekiah. Pharaoh did not act in concert with him, because he was himself compelled to retire to Egypt.
By casting up mounts ... So far from Pharaoh doing so for Jerusalem, this was what Nebuchadnezzar did against it (Jeremiah 52:4.) Colvin, Maurer, etc., refer it to Nebuchadnezzar, 'when Nebuchadnezzar shall cast up mounts.'
