Genesis 37:34-38

And Jacob rent his clothes, and put sackcloth upon his loins, and mourned for his son many days.

And all his sons and all his daughters rose up to comfort him; but he refused to be comforted; and he said, For I will go down into the grave unto my son mourning. Thus his father wept for him.

And the Midianites sold him into Egypt unto Potiphar, an officer of Pharaoh’s, and captain of the guard.
