Genesis 42:37-38

Then Reuben said to his father, “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.” But he said, “My son shall not go down with you, for his brother is dead, and he is the only one left. If harm should happen to him on the journey that you are to make, you would bring down my gray hairs with sorrow to Sheol.”
