1 Kings 13:1-3

1Now behold, there came a man of God from Judah to Bethel by the word (command) of the Lord, while Jeroboam was standing by the altar [which he had built] to burn incense.

2The man cried out against the [idolatrous] altar by the word of the Lord, “O altar, altar, thus says the Lord: ‘Behold, a son shall be born to the house of David, Josiah by name; and on you shall he sacrifice [the bodies of] the priests of the high places who burn incense on you, and human bones shall be burned on you.’ ”

3And he gave a sign the same day, saying, “This is the sign which the Lord has spoken: ‘Behold, the altar shall be split apart and the ashes that are on it shall be poured out.’ ”
