2 Kings 23:29-30

29During Josiah’s reign Pharaoh Necho king of Egypt marched toward the Euphrates River to help the king of Assyria. King Josiah marched out to fight him, but Necho killed him at Megiddo when he saw him.

30His servants transported his dead body from Megiddo in a chariot and brought it to Jerusalem, where they buried him in his tomb. The people of the land took Josiah’s son Jehoahaz, poured olive oil on his head, and made him king in his father’s place.
