Exodus 30:6-8

New Catholic Bible

⁶ And you shall place the altar in front of the veil that hides the Ark of Testimony, in front of the seat of atonement that is upon it, where I will meet you.

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.
