Exodus 30:7-9, 34-38

Aaron shall burn sweet and fragrant incense on it; he shall burn it every morning when he trims and tends the lamps. [Ps 141:2; Rev 5:8; 8:3, 4] When Aaron sets up the lamps at twilight, he shall burn incense, a perpetual incense before the LORD throughout your generations. You shall not offer any strange incense on this altar, or burnt offering or meal offering; you shall not pour out a drink offering on it.

Then the LORD said to Moses, “Take sweet and fragrant spices—stacte, onycha, and galbanum, sweet and fragrant spices with pure frankincense; there shall be an equal amount of each— and make incense with it, a perfume, the work of a perfumer, salted, pure and sacred. You shall crush some of it [into a] very fine [powder], and put some of it before the Testimony in the Tent of Meeting, where I will meet with you; it shall be most holy to you. 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 [excluding him from the atonement made for them].”
