Genesis 37:29-34

ISV(i) 29 Later, when Reuben returned to the cistern, Joseph wasn’t there! In mounting panic, he tore his clothes, 30 returned to his brothers, and shouted, “He’s not there! Now what? Where am I to go?”
31 So they took Joseph’s coat, slaughtered a young goat, and dipped the coat in the blood. 32 Then they stretched out the richly-embroidered tunic to dry, and brought it to their father.
“We’ve found this,” they reported. “Look at it and see if this is or isn’t your son’s tunic.”
33 Examining it, he cried out, “It’s my son’s tunic! A wild animal has no doubt torn Joseph to pieces.”
34 So Jacob tore his clothes, dressed himself in sackcloth, and then mourned many days for his son.
