Leviticus 6:19

It shall not be baken with leaven. I have given it [unto them for] their portion of my offerings made by fire; it [is] most holy, as [is] the sin offering, and as the trespass offering.

All the males among the children of Aaron shall eat of it. [It shall be] a statute for ever in your generations concerning the offerings of the LORD made by fire: every one that toucheth them shall be holy.

This [is] the offering of Aaron and of his sons, which they shall offer unto the LORD in the day when he is anointed; the tenth part of an ephah of fine flour for a meat offering perpetual, half of it in the morning, and half thereof at night.

In a pan it shall be made with oil; [and when it is] baken, thou shalt bring it in: [and] the baken pieces of the meat offering shalt thou offer [for] a sweet savour unto the LORD.
