These were all the sons of David
 By his wives: 
 beside the sons of the concubines;
 who are not reckoned, and how many they were is not known; he had ten concubines at least, ( 2 Samuel 15:16 ) and ( 2 Samuel 20:3 ) . 
 And Tamar their sister;
 not the sister of the sons of the concubines, but of his other sons, and only of Absalom by the mother's side, of whom see ( 2 Samuel 13:1-39 ) .
