2 Kings 1:11-13

11 And he turned and he sent to him another commander of fifty with his fifty. And he answered and said to him, Man of God! So says the king, Come down quickly.

12 And Elijah answered and said to him, If I [am] a man of God, let fire come down from the heavens and burn up you and your fifty. And the fire of God came down from the heavens and burned up him and his fifty.

13 And he turned and sent again a third commander of fifty and his fifty. And the third commander of fifty came up and fell on his knees before Elijah, and begged him, and said to him, Man of God, Please let my life and the life of these fifty, your servants, be precious in your sight.
