2 Kings 23:18 Meaning

16And as Josiah turned himself, he spied the sepulchres that were there in the mount, and sent, and took the bones out of the sepulchres, and burned them upon the altar, and polluted it, according to the word of the LORD which the man of God proclaimed, who proclaimed these words.

17Then he said, What title is that that I see? And the men of the city told him, It is the sepulchre of the man of God, which came from Judah, and proclaimed these things that thou hast done against the altar of Beth-el.

18And he said, Let him alone; let no man move his bones. So they let his bones alone, with the bones of the prophet that came out of Samaria.

19And all the houses also of the high places that were in the cities of Samaria, which the kings of Israel had made to provoke the LORD to anger, Josiah took away, and did to them according to all the acts that he had done in Beth-el.

20And he slew all the priests of the high places that were there upon the altars, and burned men's bones upon them, and returned to Jerusalem.
