Genesis 42:37-38

Reuben spoke up: “I’ll put my two sons in your hands as hostages. If I don’t bring Benjamin back, you can kill them. Trust me with Benjamin; I’ll bring him back.” But Jacob refused. “My son will not go down with you. His brother is dead and he is all I have left. If something bad happens to him on the road, you’ll put my gray, sorrowing head in the grave.”
