Genesis 42:13; Genesis 42:38

13 But they said, "Your servants are twelve brothers in all, the sons of one man in the land of Canaan; and behold, the youngest is with our father today, and one is no longer alive."

38 But Jacob said, "My son shall not go down with you; for his brother is dead, and he alone is left. If harm should befall him on the journey you are taking, then you will bring my gray hair down to Sheol in sorrow."
