Leviticus 24:5-9

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. 8Every sabbath he shall set it in order before Yhwh continually, being taken from the children of Israel by an everlasting covenant. 9And 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 Yhwh made by fire by a perpetual statute.
