'Household' in the Bible

Servants, be submissive to your masters with all [proper] respect, not only to those who are good and kind, but also to those who are unreasonable.

Finally, all of you be like-minded [united in spirit], sympathetic, brotherly, kindhearted [courteous and compassionate toward each other as members of one household], and humble in spirit;

Be hospitable to one another without complaint.

For it is the time [destined] for judgment to begin with the household of God; and if it begins with us, what will the outcome be for those who do not respect or believe or obey the gospel of God?
