Leviticus 2:2-3

²and he shall bear it to the sons of Aaron, the priest, of the which sons one of them shall take an handful of tried wheat flour, and of oil, and all the incense; and he shall put these as a memorial on the altar, into the sweetest odour to the Lord.

³Forsooth that that is left of the sacrifice shall be Aaron’s and his sons’, the holy of holy things of offerings to the Lord.
