Exodus 30:6-10

6And thou shalt put it before the veil that is by the ark of the testimony, before the mercy-seat that is over the testimony, where I will meet with thee.

7And Aaron shall burn thereon incense of sweet spices: every morning, when he dresseth the lamps, he shall burn it.

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

9Ye shall offer no strange incense thereon, nor burnt offering, nor meal offering; and ye shall pour no drink offering thereon.

10And Aaron shall make atonement upon the horns of it once in the year: with the blood of the sin offering of atonement once in the year shall he make atonement for it throughout your generations: it is most holy unto the LORD.
