'Ordinance' in the Bible

Concerning the ordinance of oil, the bath of oil, ye shall offer the tenth part of a bath out of the cor, which is an homer of ten baths; for ten baths are an homer:

And thou shalt prepare a meat offering for it every morning, the sixth part of an ephah, and the third part of an hin of oil, to temper with the fine flour; a meat offering continually by a perpetual ordinance unto the LORD.
