'Sons of David' in the Bible

And these were the sons of David which were born to him in Hebron: the first-born Amnon to Ahinoam the Jezreelitess; the second, Daniel to Abigail the Carmelitess:

All the sons of David, besides the sons of the concubines, and Tamar their sister.

And Benaiah son of Jehoiada over the Cherethites and the Pelethites; and the sons of David, heads at the hand of the king.
