Exodus 30:34-38

Then the Lord said to Moses, “Take for yourself spices—stacte, onycha, and galbanum, spices and pure frankincense; there shall be an equal part of each.

You shall make incense from it all, a skillful mixture, the work of a perfumer, salted, pure, and holy.

And you shall crush some of it very fine, and put part of it in front of the testimony in the tent of meeting where I will meet with you; it shall be most holy to you.

And 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 makes any like it, to use as perfume, shall be cut off from his people.”
