Genesis

²⁶And Judah said unto his brethren, What profit is it if we slay our brother and conceal his blood? ²⁷Come, and let us sell him to the Ishmaelites, and let not our hand be upon him; for he is our brother, our flesh. And his brethren hearkened unto him. ²⁸And there passed by Midianites, merchantmen; and they drew and lifted up Joseph out of the pit, and sold Joseph to the Ishmaelites for twenty pieces of silver. And they brought Joseph into Egypt. ²⁹And Reuben returned unto the pit; and, behold, Joseph was not in the pit; and he rent his clothes. ³⁰And he returned unto his brethren, and said, The child is not; and I, whither shall I go? ³¹And they took Joseph's coat, and killed a he-goat, and dipped the coat in the blood; ³²and 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 not.
