Genesis 37:29-34

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 he knew it, and said, It is my son's coat; an evil beast hath devoured him; Joseph is without doubt rent in pieces. And Jacob rent his clothes, and put sackcloth upon his loins, and mourned for his son many days.
