Exodus 30:7-10

New American Standard Bible

⁷ Aaron shall burn fragrant incense on it; he shall burn it every morning when he trims the lamps. ⁸ And when Aaron sets up the lamps at ^[a]twilight, he shall burn incense. There shall be perpetual incense before the Lord throughout your generations. ⁹ You shall not offer any ^[b]strange incense on ^[c]this altar, or burnt offering, or meal offering; and you shall not pour out a drink offering on it. ¹⁰ However, Aaron shall ^(A)make atonement on its horns once a year; he shall make atonement on it with the blood of the sin offering of atonement once a year throughout your generations. It is most holy to the Lord.”
