Jeremiah 37:5

Zedekiah was set up by the king of Babylon, instead of Jehoiachin, whom the king of Babylon had carried into Babylon. Zedekiah (as is usual in those cases, and as it appeareth, Ezekiel 17:16) had taken an oath of allegiance to the king of Babylon, but brake it, and the covenant which he made with him, Jeremiah 37:16 and, Jeremiah 37:15, rebelled against him, and sent his ambassador into Egypt for horses, and much people. Now the king of Egypt came in person no more after the great overthrow given him in Carchemish, by the river Euphrates, of which we read Jeremiah 46:2, which was thirteen or fourteen years before this; yet he sent an army at Zedekiah's request to relieve him, at this time besieged by the armies of the king of Babylon. The Chaldeans that were in the siege of Jerusalem hearing of it, raised the siege for a time, during which time (probably) it was that Zedekiah sent to the prophet to pray for them.
