And the land shall mourn, every family apart; the family of the house of David apart, and their wives apart; the family of the house of Nathan apart, and their wives apart; The family of the house of Levi apart, and their wives apart; the family of Shimei apart, and their wives apart; All the families that remain, every family apart, and their wives apart.
