Exodus 30:7-10 And Aaron is to burn fragrant incense on it every morning when he tends the lamps.

BSB⁽ⁱ⁾ ⁷ And Aaron is to burn fragrant incense on it every morning when he tends the lamps. ⁸ When Aaron sets up the lamps at twilight, he must burn the incense perpetually before the LORD for the generations to come. ⁹ On this altar you must not offer unauthorized incense or a burnt offering or grain offering; nor are you to pour a drink offering on it. ¹⁰ Once a year Aaron shall make atonement on the horns of the altar. Throughout your generations he shall make atonement on it annually with the blood of the sin offering of atonement. The altar is most holy to the LORD.”
