Genesis 37:29

26 And Judah said unto his brethren, What profit is it if we slay our brother, and conceal his blood?

27 Come, and let us sell him to the Ishmeelites, and let not our hand be upon him; for he is our brother and our flesh. And his brethren were content.

28 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.

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

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

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

32 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.
