Exodus 30:7-9, 34-38

And Aaron shall burn thereon incense of sweet spices: every morning, when he dresseth the lamps, he shall burn it. And when Aaron lighteth the lamps at even, he shall burn it, a perpetual incense before Jehovah throughout your generations. Ye shall offer no strange incense thereon, nor burnt-offering, nor meal-offering; and ye shall pour no drink-offering thereon.

And Jehovah said unto Moses, Take unto thee sweet spices, stacte, and onycha, and galbanum; sweet spices with pure frankincense: of each shall there be a like weight; and thou shalt make of it incense, a perfume after the art of the perfumer, seasoned with salt, pure and holy: and thou shalt beat some of it very small, and put of it before the testimony in the tent of meeting, where I will meet with thee: it shall be unto you most holy. And the incense which thou shalt make, according to the composition thereof ye shall not make for yourselves: it shall be unto thee holy for Jehovah. Whosoever shall make like unto that, to smell thereof, he shall be cut off from his people.
