30 ‘Anoint Aaron and his sons and consecrate them so they may serve me as priests. 31 Say to the Israelites, “This is to be my sacred anointing oil for the generations to come. 32 Do not pour it on anyone else’s body and do not make any other oil using the same formula. It is sacred, and you are to consider it sacred.
