Exodus 30:8-10

21st Century King James Version

⁸ And when Aaron lighteth the lamps at evening, he shall burn incense upon it, a perpetual incense before the Lord throughout your generations.

⁹ Ye shall offer no strange incense thereon, nor burnt sacrifice, nor meat offering; neither shall ye pour drink offering thereon.

¹⁰ And Aaron shall make an atonement upon the horns of it once in a year with the blood of the sin offering of atonements. Once in the year shall he make atonement upon it throughout your generations. It is most holy unto the Lord.”
