Exodus 30:7

4 And two golden rings shalt thou make to it under the crown of it, by its two corners, upon the two sides of it shalt thou make [it]; and they shall be for places for the staffs to bear it with.

5 And thou shalt make the staffs of shittim wood, and overlay them with gold.

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

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

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 upon it, nor burnt-sacrifice, nor meat-offering; neither shall ye pour drink-offering upon it.

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 a year shall he make atonement upon it throughout your generations: it [is] most holy to the LORD.
