After Josiah had done all this for the temple, King Necho of Egypt marched up to do battle at Carchemish on the Euphrates River. Josiah marched out to oppose him.

But Josiah did not turn back from him; he disguised himself for battle. He did not take seriously the words of Necho which he had received from God; he went to fight him in the Plain of Megiddo.

The king of Egypt made Jehoahaz's brother Eliakim king over Judah and Jerusalem, and changed his name to Jehoiakim. Necho seized his brother Jehoahaz and took him to Egypt.
