Exodus 30:34-38

Then the LORD said to Moses, “Take for yourself spices, stacte and onycha and galbanum, spices with pure frankincense; there shall be an equal part of each. With it you shall make incense, a perfume, the work of a perfumer, salted, pure, and holy. You shall beat some of it very fine, and put part of it before the testimony in the tent of meeting where I will meet with you; it shall be most holy to you. The incense which you shall make, you shall not make in the same proportions for yourselves; it shall be holy to you for the LORD. Whoever shall make any like it, to use as perfume, shall be cut off from his people.”
