2 Kings 1:12-14

12And Elijah answered and said to them, If I am a man of God, let fire come down from heaven, and consume thee and thy fifty. And the fire of God came down from heaven, and consumed him and his fifty. 13And 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 besought him, and said to him, O man of God, I pray thee, let my life, and the life of these fifty thy servants, be precious in thy sight.1 14Behold, 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 thy sight.
