Exodus 30:36-38

36Grind some of the mixture into a very fine powder and put it in front of the Ark of the Covenant, where I will meet with you in the Tabernacle. You must treat this incense as most holy.

37Never use this formula to make this incense for yourselves. It is reserved for the Lord, and you must treat it as holy.

38Anyone who makes incense like this for personal use will be cut off from the community.”
