Leviticus 24:5-9
5 “Take fine flour and bake twelve loaves of bread, using two-tenths of an ephah for each loaf.
6 Set them in two rows, six in each row, on the table of pure gold before the Lord.
7 Along each row put some pure incense as a memorial portion to represent the bread and to be an offering made to the Lord by fire.
8 This bread is to be set out before the Lord regularly, Sabbath after Sabbath, on behalf of the Israelites, as a lasting covenant.
9 It belongs to Aaron and his sons, who are to eat it in a holy place, because it is a most holy part of their regular share of the offerings made to the Lord by fire.”
