Exodus 30:6-10

30:6 “You are to put it in front of the curtain that is before the ark of the testimony (before the atonement lid that is over the testimony), where I will meet you. 30:7 Aaron is to burn sweet incense on it morning by morning; when he attends to the lamps he is to burn incense. 30:8 When Aaron sets up the lamps around sundown he is to burn incense on it; it is to be a regular incense offering before the Lord throughout your generations. 30:9 You must not offer strange incense on it, nor burnt offering, nor meal offering, and you must not pour out a drink offering on it. 30:10 Aaron is to make atonement on its horns once in the year with some of the blood of the sin offering for atonement; once in the year he is to make atonement on it throughout your generations. It is most holy to the Lord.”

Exodus 30:34-38

30:34 The Lord said to Moses: “Take spices, gum resin, onycha, galbanum, and pure frankincense of equal amounts 30:35 and make it into an incense, a perfume, the work of a perfumer. It is to be finely ground, and pure and sacred. 30:36 You are to beat some of it very fine and put some of it before the ark of the testimony in the tent of meeting where I will meet with you; it is to be most holy to you. 30:37 And the incense that you are to make, you must not make for yourselves using the same recipe; it is to be most holy to you, belonging to the Lord. 30:38 Whoever makes anything like it, to use as perfume, will be cut off from his people.”
