Genesis 42:35-38

35Then it happened as they emptied their sacks, that surprisingly each man’s bundle of money was in his sack; and when they and their father saw the bundles of money, they were afraid.

36And Jacob their father said to them, “You have bereaved me: Joseph is no more, Simeon is no more, and you want to take Benjamin. All these things are against me.”

37Then Reuben spoke to his father, saying, “Kill my two sons if I do not bring him back to you; put him in my hands, and I will bring him back to you.”

38But he said, “My son shall not go down with you, for his brother is dead, and he is left alone. If any calamity should befall him along the way in which you go, then you would bring down my gray hair with sorrow to the grave.”
