Exodus 30:8-10

New Revised Standard Version Catholic Edition

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.
