Charles Ellicott Commentary Jeremiah 37:7

"Thus saith Jehovah, the God of Israel, Thus shall ye say to the king of Judah, that sent you unto me to inquire of me: Behold, Pharaoh`s army, which is come forth to help you, shall return to Egypt into their own land." — Jeremiah 37:7 (ASV)

Behold, Pharaoh’s army, which is come forth to help you, shall return to Egypt. —A similar prediction regarding the fate of the Egyptian army is found in Ezekiel 17:17, and is there connected with the fact that Zedekiah’s application to Egypt was a distinct breach of the compact that he had made with the Chaldeans. Their arrival, like that of Tirhakah in the Assyrian invasion (2 Kings 19:9; Isaiah 37:9), caused only a temporary suspension of hostilities, and led finally to the conquest and subjugation of Egypt by Nebuchadnezzar.
