Exodus 30:34-38

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.”
