Genesis 37:29-32

Some time later, Reuben returned to get Joseph out of the cistern. When he discovered that Joseph was missing, he tore his clothes in grief. Then he went back to his brothers and lamented, “The boy is gone! What will I do now?” Then the brothers killed a young goat and dipped Joseph’s robe in its blood. They sent the beautiful robe to their father with this message: “Look at what we found. Doesn’t this robe belong to your son?”
