2 Kings 1:12-14

12 And Elijah answered and said to them, If I be a man of God, let fire come down from heaven, and consume you and your fifty. And the fire of God came down from heaven, and consumed him and his fifty.

13 And he sent again a captain of the third fifty with his fifty. And the third captain of fifty went up, and came and fell on his knees before Elijah, and sought him, and said to him, O man of God, I pray you, let my life, and the life of these fifty your servants, be precious in your sight.

14 Behold, there came fire down from heaven, and burnt up the two captains of the former fifties with their fifties: therefore let my life now be precious in your sight.
