Exodus 30:31-38 MSG

31 Tell the Israelites, 'This will be my holy anointing oil throughout your generations.'
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."
