What happened to the first two captains and their fifty men sent to seize Elijah?

Answer: Fire consumed them

Fire came down from heaven and consumed the first two captains and their fifties; the third captain begged for mercy.

“Elijah answered the captain, “If I am a man of God, may fire come down from heaven and consume you and your fifty men.” And fire came down from heaven and consumed the captain and his fifty men.”— 2 Kings 1:10 (BSB)
