Exodus 30:7-9, 34-38

“Aaron must burn fragrant incense on the altar every morning when he tends the lamps. He must burn incense again when he lights the lamps at twilight so incense will burn regularly before the LORD for the generations to come. Do not offer on this altar any other incense or any burnt offering or grain offering, and do not pour a drink offering on it.

Then the LORD said to Moses, “Take fragrant spices—gum resin, onycha and galbanum—and pure frankincense, all in equal amounts, and make a fragrant blend of incense, the work of a perfumer. It is to be salted and pure and sacred. 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. Do not make any incense with this formula for yourselves; consider it holy to the LORD. Whoever makes incense like it to enjoy its fragrance must be cut off from their people.”
