'Rules' in the Bible

but it is in vain they worship Me, while they lay down precepts which are mere human rules.'"

But idle is their devotion while they lay down precepts which are mere human rules.'

and one God and Father of all, who rules over all, acts through all, and dwells in all.

These rules have indeed an appearance of wisdom where self-imposed worship exists, and an affectation of humility and an ascetic severity. But not one of them is of any value in combating the indulgence of our lower natures.

But, for fear I may be hindered, I now write, so that you may have rules to guide you in dealing with God's household. For this is what the Church of the ever-living God is, and it is the pillar and foundation-stone of the truth.

And if any one takes part in an athletic contest, he gets no prize unless he obeys the rules.
