Jeremiah 37:5

Then Pharaoh's army was come forth out of Egypt: and when the Chaldeans that besieged Jerusalem heard tidings of them, they departed from Jerusalem.

Ver. 5. Then Pharaoh's army was come out of Egypt.] This, then, seemeth to be the occasion that moved Zedekiah to send to the prophet for his prayers - viz., that God would be pleased to prosper the Egyptians coming to raise the siege, and to keep off the Chaldeans from returning to Jerusalem. But God had before signified his will to the contrary; and the Jews, trusting to human helps, took not a right course for their own preservation. See Jer 34:17-22
