oikia

οἰκίᾳ [40 times](noun sg fem dat) "House" is oikia, which means "house," "building," and "household." -- The Greek word translated as "house," refers to the building itself, all the people that dwell in it, including slaves and servants, all property owned by that family, and all the descendants of the continued line.
