2 Kings 23:14, 16-20

He smashed the sacred pillars and cut down the Asherah poles. Then he desecrated these places by scattering human bones over them.

Then Josiah turned around and noticed several tombs in the side of the hill. He ordered that the bones be brought out, and he burned them on the altar at Bethel to desecrate it. (This happened just as the LORD had promised through the man of God when Jeroboam stood beside the altar at the festival.) Then Josiah turned and looked up at the tomb of the man of God who had predicted these things. “What is that monument over there?” Josiah asked. And the people of the town told him, “It is the tomb of the man of God who came from Judah and predicted the very things that you have just done to the altar at Bethel!” Josiah replied, “Leave it alone. Don’t disturb his bones.” So they did not burn his bones or those of the old prophet from Samaria. Then Josiah demolished all the buildings at the pagan shrines in the towns of Samaria, just as he had done at Bethel. They had been built by the various kings of Israel and had made the LORD very angry. He executed the priests of the pagan shrines on their own altars, and he burned human bones on the altars to desecrate them. Finally, he returned to Jerusalem.
