“David reigned thirty-three years in Jerusalem. These were born to him in Jerusalem Shimea, Shobab, Nathan and Solomon, four by Bathsheba, the daughter of Ammiel. Then the following nine children were born, Ibhar, Elishama, Eliphelet, Nogah, Nepheg, Japhia, Elishama, Eliada, and Eliphelet. All these were David’s sons, besides the sons of the concubines. Tamar was their sister.”
After David moved to Jerusalem, he took some more wives and concubines. He ruled from Jerusalem for 33 years. Once again this is taken from 2 Samuel, chapter 5. Thus there were more descendents of David than the six sons that he had at Hebron. (1) Shimea or Shammua as he was called in 2 Kings, (2) Shobab, (3) Nathan, and (4) Solomon, were the 4 sons of Bathsheba. Nathan is not the prophet mentioned later. However, Solomon followed David to the throne as king because of the intrigues of his mother Bathsheba and the prophet Nathan. The 9 other sons have unnamed mothers, (1) Ibhar, (2) Elishama, (3) Eliphelet, (4) Nogah, (5) Nepheg, (6) Japhia, (7) Elishama, (8) Eliada, and (9) Eliphelet, with 7 named in 2 Samuel. However, 2 sons, Elishama and Eliphelet were mentioned twice, unless he had 2 sons with the same name which is quite possible. The only new name is Nogah. Thus Ibhar, Nepheg, Japhia, and Eliada are other sons whose names never appear elsewhere except in the lists of David’s sons. Thus David had at least 20 named children. At the end there is the mention of only one of their sisters Tamar, who was part of the Amon and Absalom fight in 2 Samuel, chapter 13.
