Leviticus 24:5-7

5And thou shalt take fine flour, and bake twelve cakes thereof: two tenth deals shall be in one cake. 6And thou shalt set them in two rows, six on a row, upon the pure table before Yhwh. 7And 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 Yhwh.
