Exodus 29:23-28

LXX2012(i) 23 And one cake [made] with oil, and one cake from the basket of unleavened bread set forth before the Lord. 24 And you shall put them all on the hands of Aaron, and on the hands of his sons, and you shall separate them as a separate offering before the Lord. 25 And you shall take them from their hands, and shall 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. 26 And you shall take the breast from the ram of consecration which is Aaron's, and you shall separate it as a separate offering before the Lord, and it shall be to you for a portion. 27 And you shall sanctify the separated breast and the shoulder of removal which has been separated, and which has been removed from the ram of consecration, of the portion of Aaron and of [that of] his sons. 28 And it shall be a perpetual statute of the children of Israel to Aaron and his sons, for this is a separate offering; and it shall be a special offering from the children of Israel, from the peace-offerings of the children of Israel, a special offering to the Lord.
