Genesis 37:29-34

29And Reuben returned to the pit, and behold, Joseph [was] not in the pit; and he rent his garments,

30and returned to his brethren, and said, The child is not; and I, where shall I go?

31And they took Joseph's vest, and slaughtered a buck of the goats, and dipped the vest in the blood;

32and they sent the vest of many colours and had it carried to their father, and said, This have we found: discern now whether it is thy son's vest or not.

33And he discerned it, and said, [It is] my son's vest! an evil beast has devoured him: Joseph is without doubt rent in pieces!

34And Jacob rent his clothes, and put sackcloth on his loins, and mourned for his son many days.
