Exodus 30:34-38

The LORD said to Moses, “Take sweet spices, stacte, and onycha, and galbanum, sweet spices with pure frankincense (of each shall there be an equal part), and make an incense blended as by the perfumer, seasoned with salt, pure and holy. You shall beat some of it very small, and put part of it before the testimony in the tent of meeting where I shall meet with you. It shall be most holy for you. And the incense that you shall make according to its composition, you shall not make for yourselves. It shall be for you holy to the LORD. Whoever makes any like it to use as perfume shall be cut off from his people.”
