1 Kings 13:1-3

1By the word of the Lord a man of God came from Judah to Bethel, as Jeroboam was standing by the altar to make an offering. 2By the word of the Lord he cried out against the altar: “Altar, altar! This is what the Lord says: ‘A son named Josiah will be born to the house of David. On you he will sacrifice the priests of the high places who make offerings here, and human bones will be burned on you.’ ” 3That same day the man of God gave a sign: “This is the sign the Lord has declared: The altar will be split apart and the ashes on it will be poured out.”
