broken the arm] This hath relation to the first overthrow of the Egyptians under Neco at Carchemish, Jeremiah 46:2. by which they lost a great part which they possessed out of Egypt; which is the broken arm: and there remained nothing to them but Egypt alone; which was the whole or sound arm. And after this losse they could never recover, nor defend themselves against the Chaldeans. See Chap. 29. 14, 15. it shall not be bound up] Jeremiah 46:11.
