Leviticus 24:7-9

Revised Standard Version

⁷ And you shall put pure frankincense with each row, that it may go with the bread as a memorial portion to be offered by fire to the Lord. ⁸ Every sabbath day Aaron shall set it in order before the Lord continually on behalf of the people of Israel as a covenant for ever. ⁹ And it shall be for Aaron and his sons, and they shall eat it in a holy place, since it is for him a most holy portion out of the offerings by fire to the Lord, a perpetual due.”
