Nathan was the son of David. Nathan was one of more than nineteen sons that were born to David and his eight wives. This number did not include the unnamed offspring of David and his concubines.
Nothing is known about Nathan’s life. It is possible—though entirely speculative—that he was named in honor of the prophet who served David so well throughout his reign.
What is most remarkable about Nathan is that he was one of four sons born to David and Bathsheba, the wife who never should have been his.
David reigned in Jerusalem thirty-three years, and these were the children born to him there: Shammua, Shobab, Nathan and Solomon. These four were by Bathsheba daughter of Ammiel.1 CHRONICLES 3:4–5
David’s crime, however, did not escape notice. The prophet Nathan confronted the king. David confessed, but he and Bathsheba were punished with the loss of the child that had been conceived in the adulterous affair. At this point, David might have easily scorned Bathsheba, regarding her as too painful a reminder of his indiscretion. Instead, David chose to comfort his bereaved wife, and in His mercy, God gave the couple four sons—one of whom was Nathan.
The Gospel of Luke traces Jesus’ genealogy through Nathan, son of David and Bathsheba .
The son of Melea, the son of Menna, the son of Mattatha, the son of Nathan, the son of David,( Luke 3:31).
