Exodus 30:31
And thou shalt speak unto the children of Israel, saying, This shall be an holy anointing oil unto me throughout your generations. And thou shalt speak unto the children of Israel, saying, This shall be an holy anointing oil unto me throughout your generations.
The anointing oil was a special preparation made and set apart for use in the tabernacle. It was to be a holy anointing oil to God throughout the generations of Israel. The distinction between what was sacred and what was common in its regard was to be strictly observed.
