Exodus 29:23

²¹And thou shalt take of the blood from the altar, and of the anointing oil; and thou shalt sprinkle it upon Aaron and on his garments, and on his sons and on his sons’ garments with him; and he shall be sanctified and his apparel, and his sons and his sons’ apparel with him: but the blood of the ram thou shalt pour round about upon the altar.

²²And thou shalt take from the ram its fat, both the fat that covers the belly, and the lobe of the liver, and the two kidneys, and the fat that is upon them, and the right shoulder, for this is a consecration.

— Exodus 29:23 —

²⁴And thou shalt put them all on the hands of Aaron, and on the hands of his sons, and thou shalt separate them as a separate offering before the Lord.

²⁵And thou shalt take them from their hands, and shalt offer them up on the altar of whole burnt offering for a sweet-smelling savor before the Lord: it is an offering to the Lord.
