'Ordinance' in the Bible

Because you did not carry it at the first, the Lord our God made an outburst on us, for we did not seek Him according to the ordinance.”

and to offer all burnt offerings to the Lord, on the sabbaths, the new moons and the fixed festivals in the number set by the ordinance concerning them, continually before the Lord.

These were their offices for their ministry when they came in to the house of the Lord according to the ordinance given to them through Aaron their father, just as the Lord God of Israel had commanded him.
