2 Kings 23:28-29

28As for the other events of Josiah’s reign, and all he did, are they not written in the book of the annals of the kings of Judah? 29While Josiah was king, Pharaoh Necho king of Egypt went up to the Euphrates River to help the king of Assyria. King Josiah marched out to meet him in battle, but Necho faced him and killed him at Megiddo.
