Genesis 37:29-36

Then Reuben returned to the pit, and indeed Joseph was not in the pit; and he tore his clothes. And he returned to his brothers and said, “The lad is no more; and I, where shall I go?” So they took Joseph’s tunic, killed a kid of the goats, and dipped the tunic in the blood. Then they sent the tunic of many colors, and they brought it to their father and said, “We have found this. Do you know whether it is your son’s tunic or not?” And he recognized it and said, “It is my son’s tunic. A wild beast has devoured him. Without doubt Joseph is torn to pieces.” Then Jacob tore his clothes, put sackcloth on his waist, and mourned for his son many days. And all his sons and all his daughters arose to comfort him; but he refused to be comforted, and he said, “For I shall go down into the grave to my son in mourning.” Thus his father wept for him. Now the Midianites had sold him in Egypt to Potiphar, an officer of Pharaoh and captain of the guard.
