Leviticus 2:15

And when any will offer a meat offering unto the LORD, his offering shall be of fine flour; and he shall pour oil upon it, and put frankincense thereon:

And he shall bring it to Aaron's sons the priests: and he shall take thereout his handful of the flour thereof, and of the oil thereof, with all the frankincense thereof; and the priest shall burn the memorial of it upon the altar, to be an offering made by fire, of a sweet savour unto the LORD:

And the remnant of the meat offering shall be Aaron's and his sons': it is a thing most holy of the offerings of the LORD made by fire.

And if thou bring an oblation of a meat offering baken in the oven, it shall be unleavened cakes of fine flour mingled with oil, or unleavened wafers anointed with oil.
