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. 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 that it may be a memorial portion for the bread, even 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. 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.”
