2 Kings 23:14, 16-20

Josiah smashed the sacred stones and cut down the Asherah poles and covered the sites with human bones.

Then Josiah looked around, and when he saw the tombs that were there on the hillside, he had the bones removed from them and burned on the altar to defile it, in accordance with the word of the LORD proclaimed by the man of God who foretold these things. The king asked, “What is that tombstone I see?” The people of the city said, “It marks the tomb of the man of God who came from Judah and pronounced against the altar of Bethel the very things you have done to it.” “Leave it alone,” he said. “Don’t let anyone disturb his bones.” So they spared his bones and those of the prophet who had come from Samaria. Just as he had done at Bethel, Josiah removed all the shrines at the high places that the kings of Israel had built in the towns of Samaria and that had aroused the LORD’s anger. Josiah slaughtered all the priests of those high places on the altars and burned human bones on them. Then he went back to Jerusalem.
