2 Kings 1:10-12

10But Elijah replied to the captain of fifty, “If I am a man of God, 1may fire come down from heaven and consume you and your fifty.” 2Then fire came down from heaven and consumed him and his fifty men.

11So the king again sent to him another captain of fifty with his fifty men. And he said to him, “You man of God, this is what the king says: ‘Come down quickly!’” 12But Elijah replied to them, “If I am a man of God, may fire come down from heaven and consume you and your fifty.” Then the fire of God came down from heaven and consumed him and his fifty men.
