Exodus 30:34-38 New International Version (NIV)

Incense

³⁴ Then the Lord said to Moses, “Take fragrant spices—gum resin, onycha and galbanum—and pure frankincense, all in equal amounts, ³⁵ and make a fragrant blend of incense, the work of a perfumer. It is to be salted and pure and sacred. ³⁶ Grind some of it to powder and place it in front of the ark of the covenant law in the tent of meeting, where I will meet with you. It shall be most holy to you. ³⁷ Do not make any incense with this formula for yourselves; consider it holy to the Lord. ³⁸ Whoever makes incense like it to enjoy its fragrance must be cut off from their people.”
