Exodus 30:8-10

New Catholic Bible

⁸ and also in the evening when he refills the lamps. There shall be perpetual incense before the Lord throughout all your generations. ⁹ Do not offer any unholy incense upon it, nor burnt offerings nor sacrifices nor libations. ¹⁰ Once a year Aaron shall perform an atonement ritual upon it, upon its horns. He shall make atonement upon it with the blood of your sin offering once a year throughout all your generations. It is something most holy to the Lord.”
