Genesis 37:31-36

Then they took Joseph’s tunic, slaughtered a male goat and dipped the tunic in the blood; and they brought the multicolored tunic to their father, saying, “We have found this; please examine it and decide whether or not it is your son’s tunic.” He recognized it and said, “It is my son’s tunic. A wild animal has devoured him; Joseph is without doubt torn in pieces!” So Jacob tore his clothes [in grief], put on sackcloth and mourned many days for his son. Then all his sons and daughters attempted to console him, but he refused to be comforted and said, “I will go down to Sheol (the place of the dead) in mourning for my son.” And his father wept for him. Meanwhile, in Egypt the Midianites sold Joseph [as a slave] to Potiphar, an officer of Pharaoh and the captain of the [royal] guard.
