And in Jerusalem he reigned thirty and three years; and these were born unto him in Jerusalem: Shimea, and Shobab, and Nathan, and Solomon, four, of Bath-shua the daughter of Ammiel; and Ibhar, and Elishama, and Eliphelet, and Nogah, and Nepheg, and Japhia, and Elishama, and Eliada, and Eliphelet, nine. All these were the sons of David, besides the sons of the concubines; and Tamar was their sister.
