1 Kings 13:1-3

At the LORD’s command, a man of God from Judah went to Bethel, arriving there just as Jeroboam was approaching the altar to burn incense. Then at the LORD’s command, he shouted, “O altar, altar! This is what the LORD says: A child named Josiah will be born into the dynasty of David. On you he will sacrifice the priests from the pagan shrines who come here to burn incense, and human bones will be burned on you.” That same day the man of God gave a sign to prove his message. He said, “The LORD has promised to give this sign: This altar will split apart, and its ashes will be poured out on the ground.”
