Genesis 37:28-36

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. They sent the beautiful robe to their father with this message: “Look at what we found. Doesn’t this robe belong to your son?” Their father recognized it immediately. “Yes,” he said, “it is my son’s robe. A wild animal must have eaten him. Joseph has clearly been torn to pieces!” Then Jacob tore his clothes and dressed himself in burlap. He mourned deeply for his son for a long time. His family all tried to comfort him, but he refused to be comforted. “I will go to my grave mourning for my son,” he would say, and then he would weep. Meanwhile, the Midianite traders arrived in Egypt, where they sold Joseph to Potiphar, an officer of Pharaoh, the king of Egypt. Potiphar was captain of the palace guard.
