Leviticus 24:7-9

Young's Literal Translation

⁷ and thou hast put on the rank pure frankincense, and it hath been to the bread for a memorial, a fire-offering to Jehovah.

⁸ `On each sabbath-day he arrangeth it before Jehovah continually, from the sons of Israel -- a covenant age-during;

⁹ and it hath been to Aaron, and to his sons, and they have eaten it in the holy place, for it [is] most holy to him, from the fire-offerings of Jehovah -- a statute age-during.'
