Bible: Lev. 8:22-24
8:22 Then he presented the second ram, the ram of ordination, 1 and Aaron and his sons laid their hands on the head of the ram 8:23 and he slaughtered it. 2 Moses then took some of its blood and put it on Aaron’s right earlobe, 3 on the thumb of his right hand, and on the big toe 4 of his right foot. 8:24 Next he brought Aaron’s sons forward, and Moses put some of the blood on their right earlobes, on their right thumbs, and on the big toes of their right feet, and Moses splashed the rest of the blood against the altar’s sides.
