Leviticus 7:34-36

New Century Version

³⁴ I have taken the breast and the thigh from the fellowship offerings of the Israelites, and I have given these parts to Aaron and the priests as their share for all time from the Israelites.’”

³⁵ This is the portion that belongs to Aaron and his sons from the offerings made by fire to the Lord. They were given this share on the day they were presented to the Lord as priests. ³⁶ On the day the Lord appointed the priests, he commanded Israel to give this share to them, and it is to be given to the priests as their share from now on.
