'House' in the Bible

conducting his own house well, having his children in subjection with all gravity;

(but if one does not know how to conduct his own house, how shall he take care of the assembly of God?)

but if I delay, in order that thou mayest know how one ought to conduct oneself in God's house, which is the assembly of the living God, the pillar and base of the truth.

but if any widow have children or descendants, let them learn first to be pious as regards their own house, and to render a return on their side to their parents; for this is acceptable in the sight of God.

But if any one does not provide for his own, and specially for those of his house, he has denied the faith, and is worse than the unbeliever.

I will therefore that the younger marry, bear children, rule the house, give no occasion to the adversary in respect of reproach.
