Genesis 37:29-32

When Reuben returned to the cistern and saw that Joseph was not there, he tore his clothes. He went back to his brothers and said, “The boy isn’t there! Where can I turn now?” 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.”
