'Household' in the Bible

one who manages his own household competently, having his children under control with all dignity.

(If anyone does not know how to manage his own household, how will he take care of God’s church?)

But if I should be delayed, I have written so that you will know how people ought to act in God’s household, which is the church of the living God, the pillar and foundation of the truth.

But if anyone does not provide for his own, that is his own household, he has denied the faith and is worse than an unbeliever.
