Leviticus 24:7

⁵  And thou shalt take fine flour, and bake twelve cakes thereof: two tenth deals shall be in one cake.

⁶  And thou shalt set them in two rows, six on a row, upon the pure table before the LORD.

⁷  And thou shalt put pure frankincense upon each row, that it may be on the bread for a memorial, even an offering made by fire unto the LORD.

⁸  Every sabbath he shall set it in order before the LORD continually, being taken from the children of Israel by an everlasting covenant.

⁹  And it shall be Aaron's and his sons'; and they shall eat it in the holy place: for it is most holy unto him of the offerings of the LORD made by fire by a perpetual statute.
