'Rules' in the Bible

one who rules his own house well, having children in subjection with all reverence;

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.

I solemnly charge you in the presence of God and of Christ Jesus and of His chosen angels that you guard and keep these rules without bias, doing nothing out of favoritism.
