Genesis 37:27-31

Instead of hurting him, let’s sell him to those Ishmaelite traders. After all, he is our brother—our own flesh and blood!” And his brothers agreed. So when the Ishmaelites, who were Midianite traders, came by, Joseph’s brothers pulled him out of the cistern and sold him to them for twenty pieces of silver. And the traders took him to Egypt. 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.
