'Household' in the Bible

Who are you to criticize another’s household slave? Before his own Lord he stands or falls. And he will stand. For the Lord is able to make him stand.

Greet Apelles, who is approved in Christ.Greet those who belong to the household of Aristobulus.

Greet Herodion, my fellow countryman.Greet those who belong to the household of Narcissus who are in the Lord.
