Exodus 29:19-20

19“Then 1you shall take the 2other ram, and Aaron and his sons shall lay their hands on the head of the ram.

20And you shall slaughter the ram, and take some of its blood and put it on the lobe of Aaron’s right ear and on the lobes of his sons’ right ears, and on the thumbs of their right hands, and on the big toes of their right feet, and sprinkle the rest of the blood around on the altar.
