Exodus 30:7-9

New Catholic Bible

⁷ “Aaron shall burn fragrant incense upon the altar. He shall burn it each morning when he trims the lamps, 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.
