Exodus 30:7-9
7 Aaron must burn fragrant incense on it; he must burn it every morning when he tends the lamps.(A)
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,(B) or a burnt or grain offering; you are not to pour a drink offering on it.
