Exodus 30:7-9, 34-38

“Aaron shall burn on it sweet incense every morning; when he tends the lamps, he shall burn incense on it. And when Aaron lights the lamps at twilight, he shall burn incense on it, a perpetual incense before the LORD throughout your generations. You shall not offer strange incense on it, or a burnt offering, or a grain offering; nor shall you pour a drink offering on it.

And the LORD said to Moses: “Take sweet spices, stacte and onycha and galbanum, and pure frankincense with these sweet spices; there shall be equal amounts of each. You shall make of these an incense, a compound according to the art of the perfumer, salted, pure, and holy. And you shall beat some of it very fine, and put some of it before the Testimony in the tabernacle of meeting where I will meet with you. It shall be most holy to you. But as for the incense which you shall make, you shall not make any for yourselves, according to its composition. It shall be to you holy for the LORD. Whoever makes any like it, to smell it, he shall be cut off from his people.”
