At the LORD's command, a man of God from Judah went to Bethel, and he arrived there just as Jeroboam was approaching the altar to offer a sacrifice.
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, and 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."
King Jeroboam was very angry with the man of God for speaking against the altar. So he pointed at the man and shouted, "Seize that man!" But instantly the king's hand became paralyzed in that position, and he couldn't pull it back.
At the same time a wide crack appeared in the altar, and the ashes poured out, just as the man of God had predicted in his message from the LORD.
The king cried out to the man of God, "Please ask the LORD your God to restore my hand again!" So the man of God prayed to the LORD, and the king's hand became normal again.
