Leviticus 10:13

¹¹and to teach the children of Israel all the statutes, which the Lord spoke to them by Moses.

¹²And Moses said to Aaron, and to Eleazar and Ithamar, the sons of Aaron who survived, Take the sacrifice that is left of the burnt offerings of the Lord, and ye shall eat unleavened bread by the altar: it is most holy.

— Leviticus 10:13 —

¹⁴And ye shall eat the breast of separation, and the shoulder of the choice offering in the holy place, thou and thy sons and thy house with thee; for it has been given as an ordinance for thee and an ordinance for thy sons, of the sacrifices of peace offering of the children of Israel.

¹⁵They shall bring the shoulder of the choice offering, and the breast of the separation upon the burnt offerings of the fat, to separate for a separation before the Lord; and it shall be a perpetual ordinance for thee and thy sons and thy daughters with thee, as the Lord commanded Moses.
