Exodus 30:30-32 GOD’S WORD Translation (GW)
30 Anoint Aaron and his sons as well. In this way you will set them apart for their holy duties of serving me as priests.
31 “Say to the Israelites, ‘For generations to come, this will be my holy oil used only for anointing. 32 It must never be poured on the bodies of other people. Never make any perfumed oil using this formula. It is holy, and you must treat it as holy.
