'House' in the Bible

one that ruleth well his own house, having his children in subjection with all gravity;

(but if a man knoweth not how to rule his own house, how shall he take care of the church of God?)

but if I tarry long, that thou mayest know how men ought to behave themselves in the house of God, which is the church of the living God, the pillar and ground of the truth.

And withal they learn also to be idle, going about from house to house; and not only idle, but tattlers also and busybodies, speaking things which they ought not.
