2 Kings 23:16-17

Then Josiah, turning round, saw on the mountain the places of the dead, and he sent and had the bones taken out of their places and burned on the altar, so making it unclean, as the Lord had said by the man of God when Jeroboam was in his place by the altar on that feast-day. And he, turning his eyes to the resting-place of the man of God who had given word of these things, said: What is that headstone I see over there? And the men of the town said to him, It is the resting-place of the man of God who came from Judah and gave word of all these things which you have done to the altar of Beth-el.
