Genesis 37:29-33 NASB
29 Now Reuben returned to the pit, and behold, Joseph was not in the pit; so he tore his garments. 30 He returned to his brothers and said, “The boy is not there; as for me, where am I to go?” 31 So they took Joseph’s tunic, and slaughtered a male goat and dipped the tunic in the blood; 32 and they sent the varicolored tunic and brought it to their father and said, “We found this; please [v]examine it to see whether it is your son’s tunic or not.” 33 Then he [w]examined it and said, “It is my son’s tunic. A wild beast has devoured him; Joseph has surely been torn to pieces!”
