'Household' in the Bible

Household slaves, submit with all fear to your masters, not only to the good and gentle but also to the cruel.

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 the time has come for judgment to begin with God’s household, and if it begins with us, what will the outcome be for those who disobey the gospel of God?
