Exodus 30:32-38 MSG

32 Don't pour it on ordinary men. Don't copy this mixture to use for yourselves. It's holy; keep it holy.
33 Whoever mixes up anything like it, or puts it on an ordinary person, will be expelled." Holy Incense
34 God spoke to Moses: "Take fragrant spices - gum resin, onycha, galbanum - and add pure frankincense. Mix the spices in equal proportions
35 to make an aromatic incense, the art of a perfumer, salted and pure - holy.
36 Now crush some of it into powder and place some of it before The Testimony in the Tent of Meeting where I will meet with you; it will be for you the holiest of holy places.
37 When you make this incense, you are not to copy the mixture for your own use. It's holy to God; keep it that way.
38 Whoever copies it for personal use will be excommunicated."
