Amplified Bible

⁷ Aaron shall burn sweet and fragrant incense on it; he shall burn it every morning when he trims and tends the lamps.^{(A) 8} When Aaron sets up the lamps at twilight, he shall burn incense, a perpetual incense before the Lord throughout your generations. ⁹ You shall not offer any strange incense on this altar, or burnt offering or meal offering; you shall not pour out a drink offering on it.
