Genesis 37:28-32 King James Version (KJV)
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.
