Leviticus 2:11 No meat offering, which ye shall bring unto the Lord, shall be made with leaven: for ye shall burn no leaven, nor any honey, in any offering of the Lord made by fire. 12 I MC VC

Leviticus 6:17 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. 10 I MC VC
