Leviticus 24:7

5“You shall take fine flour, and bake twelve cakes of it: two tenths of an ephah shall be in one cake.

6You shall set them in two rows, six on a row, on the pure gold table before the LORD.

7You shall put pure frankincense on each row, that it may be to the bread for a memorial, even an offering made by fire to the LORD.

8Every Sabbath day he shall set it in order before the LORD continually. It is an everlasting covenant on the behalf of the children of Israel.

9It shall be for Aaron and his sons. They shall eat it in a holy place; for it is most holy to him of the offerings of the LORD made by fire by a perpetual statute.”
