Exodus 30:30-34

You shall anoint Aaron and his sons, and consecrate them, that they may minister as priests to Me. You shall speak to the sons of Israel, saying, ‘This shall be a holy anointing oil to Me throughout your generations. It shall not be poured on anyone’s body, nor shall you make any like it in the same proportions; it is holy, and it shall be holy to you. Whoever shall mix any like it or whoever puts any of it on a layman shall be cut off from his people.’ ” Then the LORD said to Moses, “Take for yourself spices, stacte and onycha and galbanum, spices with pure frankincense; there shall be an equal part of each.
