Genesis 37:26-34 NRSV
Then Judah said to his brothers, “What profit is it if we kill our brother and conceal his blood? Come, let us sell him to the Ishmaelites, and not lay our hands on him, for he is our brother, our own flesh.” And his brothers agreed. When some Midianite traders passed by, they drew Joseph up, lifting him out of the pit, and sold him to the Ishmaelites for twenty pieces of silver. And they took Joseph to Egypt.
When Reuben returned to the pit and saw that Joseph was not in the pit, he tore his clothes. He returned to his brothers, and said, “The boy is gone; and I, where can I turn?” Then they took Joseph's robe, slaughtered a goat, and dipped the robe in the blood. They had the long robe with sleeves taken to their father, and they said, “This we have found; see now whether it is your son's robe or not.” He recognized it, and said, “It is my son's robe! A wild animal has devoured him; Joseph is without doubt torn to pieces.” Then Jacob tore his garments, and put sackcloth on his loins, and mourned for his son many days.
