Genesis 37:31-33

31Then they got Joseph’s robe, slaughtered a goat and dipped the robe in the blood.

32They took the ornate robe back to their father and said, “We found this. Examine it to see whether it is your son’s robe.”

33He recognized it and said, “It is my son’s robe! Some ferocious animal has devoured him. Joseph has surely been torn to pieces.”
