Exodus 30:30-34

“Anoint Aaron and his sons also, consecrating them to serve me as priests. And say to the people of Israel, ‘This holy anointing oil is reserved for me from generation to generation. It must never be used to anoint anyone else, and you must never make any blend like it for yourselves. It is holy, and you must treat it as holy. Anyone who makes a blend like it or anoints someone other than a priest will be cut off from the community.’” Then the LORD said to Moses, “Gather fragrant spices—resin droplets, mollusk shell, and galbanum—and mix these fragrant spices with pure frankincense, weighed out in equal amounts.
