Exodus 30:7-10 ▼

7 Aaron must burn fragrant incense on it; he must burn it every morning when he tends the lamps.

8 When Aaron sets up the lamps at twilight, he must burn incense. There is to be an incense offering before the LORD throughout your generations.

9 You must not offer unauthorized incense on it, or a burnt or grain offering; you are not to pour a drink offering on it.”

10 Once a year Aaron is to perform the purification rite on the horns of the altar. Throughout your generations he is to perform the purification rite for it once a year, with the blood of the sin offering for atonement. The altar is especially holy to the LORD.”
