'Ordinance' in the Bible

For because ye bare it not at the first, Jehovah our God made a breach upon us, for that we sought him not according to the ordinance.

and to offer all burnt-offerings unto Jehovah, on the sabbaths, on the new moons, and on the set feasts, in number according to the ordinance concerning them, continually before Jehovah;

This was the ordering of them in their service, to come into the house of Jehovah according to the ordinance given unto them by Aaron their father, as Jehovah, the God of Israel, had commanded him.
