And it came to pass, when king Jeroboam heard the saying of the man of God, which had cried against the altar in Bethel, that he put forth his hand from the altar, saying, Lay hold on him. And his hand, which he put forth against him, dried up, so that he could not pull it in again to him. And the king answered and said unto the man of God, Intreat now the face of the LORD thy God, and pray for me, that my hand may be restored me again. And the man of God besought the LORD, and the king's hand was restored him again, and became as it was before.
