Leviticus 8:28

And Moses took the breast, and separated it for a heave-offering before the Lord, from the ram of consecration; and it became Moses' portion, as the Lord commanded Moses.

And Moses took them from off their hands, and burnt them on the altar upon the burnt offering: they were consecrations for a sweet savour: it is an offering made by fire unto the Lord.

Moses took them from their hands, and burned them on the altar on the burnt offering. They were a consecration offering for a pleasant aroma. It was an offering made by fire to Yahweh.
