Leviticus 24:5-9

“Then you shall take fine flour and bake twelve cakes with it; two-tenths of an ephah shall be in each cake.

And you shall set them in two rows, six to a row, on the pure gold table before the Lord.

You shall put pure frankincense on each row so that it may be a memorial portion for the bread, an offering by fire to the Lord.

Every Sabbath day he shall set it in order before the Lord continually; it is an everlasting covenant for the sons of Israel.

And it shall be for Aaron and his sons, and they shall eat it in a holy place; for it is most holy to him from the Lord’s offerings by fire, his portion forever.”
