Lev 24:5-9

The Bread for the Tabernacle 5You shall take choice flour, and bake twelve loaves of it; two-tenths of an ephah shall be in each loaf.6You shall place them in two rows, six in a row, on the table of pure gold.7You shall put pure frankincense with each row, to be a token offering for the bread, as an offering by fire to the Lord.8Every sabbath day Aaron shall set them in order before the Lord regularly as a commitment of the people of Israel, as a covenant forever.9They shall be for Aaron and his descendants, who shall eat them in a holy place, for they are most holy portions for him from the offerings by fire to the Lord, a perpetual due.
