Genesis 37:33 (KJV)

Then there passed by Midianites merchantmen; and they drew and lifted up Joseph out of the pit, and sold Joseph to the Ishmeelites for twenty pieces of silver: and they brought Joseph into Egypt.

And Reuben returned unto the pit; and, behold, Joseph was not in the pit; and he rent his clothes.

And he returned unto his brethren, and said, The child is not; and I, whither shall I go?

And they took Joseph's coat, and killed a kid of the goats, and dipped the coat in the blood;

And they sent the coat of many colours, and they brought it to their father; and said, This have we found: know now whether it be thy son's coat or no.

And Jacob rent his clothes, and put sackcloth upon his loins, and mourned for his son many days.

And all his sons and all his daughters rose up to comfort him; but he refused to be comforted; and he said, For I will go down into the grave unto my son mourning. Thus his father wept for him.

And the Midianites sold him into Egypt unto Potiphar, an officer of Pharaoh's, and captain of the guard.
