Genesis 37:31-34

Then they got Joseph’s robe, slaughtered a goat and dipped the robe in the blood. They took the ornate robe back to their father and said, “We found this. Examine it to see whether it is your son’s robe.” He recognized it and said, “It is my son’s robe! Some ferocious animal has devoured him. Joseph has surely been torn to pieces.” Then Jacob tore his clothes, put on sackcloth and mourned for his son many days.
