'Ordinance' in the Bible

and they are ministering before the tabernacle of the tent of meeting, in song, till the building by Solomon of the house of Jehovah in Jerusalem; and they stand according to their ordinance over their service.

because at the first it was not ye, Jehovah our God made a breach upon us, because we sought Him not according to the ordinance.'

He confirmed it to Jacob in the form of an ordinance, an eternal covenant to Israel,

and for all the burnt-offerings -- burnt-offerings to Jehovah for sabbaths, for new moons, and for appointed seasons, by number, according to the ordinance upon them continually, before Jehovah.

These are their appointments for their service, to come in to the house of Jehovah, according to their ordinance by the hand of Aaron their father, as Jehovah God of Israel, commanded them.
