Exodus 30:8-10

New Revised Standard Version, Anglicised

⁸ and when Aaron sets up the lamps in the evening he shall offer it, a regular incense-offering before the Lord throughout your generations. ⁹ You shall not offer unholy incense on it, or a burnt-offering, or a grain-offering; and you shall not pour a drink-offering on it. ¹⁰ Once a year Aaron shall perform the rite of atonement on its horns. Throughout your generations he shall perform the atonement for it once a year with the blood of the atoning sin-offering. It is most holy to the Lord.
