Leviticus 2:2-4

Living Bible

² Then he is to take a handful, representing the entire amount,^[a] to one of the priests to burn, and the Lord will be fully pleased. ³ The remainder of the flour is to be given to Aaron and his sons as their food; but all of it is counted as a holy burnt offering to the Lord.

⁴ “If bread baked in the oven is brought as an offering to the Lord, it must be made from finely ground flour, baked with olive oil but without yeast. Wafers made without yeast and spread with olive oil may also be used as an offering.
