John Gill Commentary Ezekiel 30:24

"And I will strengthen the arms of the king of Babylon, and put my sword in his hand: but I will break the arms of Pharaoh, and he shall groan before him with the groanings of a deadly wounded man." — Ezekiel 30:24 (ASV)

And I will strengthen the arms of the king of Babylon Give him a commission to make war; direct his councils; supply him with all necessaries; animate and encourage his soldiers; and give him success in all his enterprises:

and put my sword in his hand ; which confirms the above sense, that he should have power and authority from the Lord to attack the king of Egypt, and should gain a victory over him; since it was not his own sword he drew, but the sword of the Lord of hosts; which coming from him, and having his commission, cannot fail of doing execution;

but will break Pharaoh's arms ; as before in (Ezekiel 30:21Ezekiel 30:22) :

and he shall groan before him with the groanings of a deadly wounded man ; that is, before the king of Babylon; by whom, as an instrument, his arms shall be broken, and his power destroyed; and he be like a man in the agonies of death, just expiring, not able to speak, but groaning out his life under the inexpressible anguish of broken bones, and none to set them.
