Genesis 37:29-34

37:29 Later Reuben returned to the cistern to find that Joseph was not in it! He tore his clothes, 37:30 returned to his brothers, and said, “The boy isn’t there! And I, where can I go?” 37:31 So they took Joseph’s tunic, killed a young goat, and dipped the tunic in the blood. 37:32 Then they brought the special tunic to their father and said, “We found this. Determine now whether it is your son’s tunic or not.”

37:33 He recognized it and exclaimed, “It is my son’s tunic! A wild animal has eaten him! Joseph has surely been torn to pieces!” 37:34 Then Jacob tore his clothes, put on sackcloth, and mourned for his son many days.
