Exodus 30:7-9

Revised Standard Version

⁷ And Aaron shall burn fragrant incense on it; every morning when he dresses the lamps he shall burn it, ⁸ and when Aaron sets up the lamps in the evening, he shall burn it, a perpetual incense before the Lord throughout your generations. ⁹ You shall offer no unholy incense thereon, nor burnt offering, nor cereal offering; and you shall pour no libation thereon.
