Genesis 37:31-36

And they took Joseph's coat, and killed a kid of the goats, and dipped the coat in the blood; and they sent the coat of many colours, and they brought it to their father; and said, This have we found: know now whether it be thy son's coat or no. And he knew it, and said, It is my son's coat; an evil beast hath devoured him; Joseph is without doubt rent in pieces. 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.
