Exodus 29:24

21 Then take some of the blood on the altar, and the oil, and put it on Aaron and his robes and on his sons and on their robes, so that he and his robes and his sons and their robes may be made holy.

22 Then take the fat of the sheep, the fat tail, the fat covering the insides, and the fat joining the liver and the two kidneys with the fat round them, and the right leg; for by the offering of this sheep they are to be marked out as priests:

23 And take one bit of bread and one cake of oiled bread and one thin cake out of the basket of unleavened bread which is before the Lord:

24 And put them all on the hands of Aaron and of his sons, to be waved for a wave offering before the Lord.

25 Then take them from their hands, and let them be burned on the burned offering on the altar, a sweet smell before the Lord, an offering made by fire to the Lord.

26 Then take the breast of Aaron's sheep, waving it before the Lord; and it is to be your part of the offering.

27 So you are to make holy the breast of the sheep which is waved and the leg which is lifted up on high, that is, of the sheep which is offered for Aaron and his sons;
