'Rule' in the Bible

And you may take no bread or dry grain or new grain for food till the very day on which you have given the offering for your God: this is a rule for ever through all your generations wherever you are living

And on the same day, let it be given out that there will be a holy meeting for you: you may do no field-work on that day: it is a rule for ever through all your generations wherever you are living

And let this feast be kept before the Lord for seven days in the year: it is a rule for ever from generation to generation; in the seventh month let it be kept.

Outside the veil of the ark in the Tent of meeting; let Aaron see that it is burning from evening till morning at all times before the Lord: it is a rule for ever through all your generations.

And it will be for Aaron and his sons; they are to take it for food in a holy place: it is the most holy of all the offerings made by fire to the Lord, a rule for ever.
