2 Kings 23:25-29

Before him there was no king like Josiah who turned to the Lord with all his heart and all his soul and all his might, in accordance with all the Law of Moses; nor did anyone like him arise after him.

However, the Lord did not turn from the fierceness of His great wrath which was kindled against Judah because of all the despicable acts with which Manasseh had provoked Him.

The Lord said, “I will also remove Judah from My sight, just as I have removed Israel; and will reject this city which I have chosen, this Jerusalem, and the house, of which I said, ‘My Name [and the pledge of My Presence] shall be there.’ ”Jehoahaz Succeeds Josiah

Now the rest of the acts of Josiah, everything that he did, are they not written in the Book of the Chronicles of the Kings of Judah?

In his days Pharaoh Neco (Necho) king of Egypt went up to the king of Assyria to the river Euphrates [to help him fight Nabopolassar the king of Babylon]. King Josiah went out to meet him, but Pharaoh killed Josiah at Megiddo when he saw him.
