Genesis 37:30-34

He returned to his brothers and said, “The boy is not there; as for me, where am I to go?”

So they took Joseph’s tunic, and slaughtered a male goat, and dipped the tunic in the blood;

and they sent the multicolored tunic and brought it to their father and said, “We found this; please examine it to see whether it is your son’s tunic or not.”

Then he examined it and said, “It is my son’s tunic. A vicious animal has devoured him; Joseph has surely been torn to pieces!”

So Jacob tore his clothes, and put on a sackcloth undergarment over his waist, and mourned for his son many days.
