Who was the 5th wife of King David?

       Haggith (II Sam. 3:4; I Kings 1:5, 11; 2:13; I Chron. 3:2), the fifth wife of David and mother of his fourth son Adonijah. In the five places that Haggith is mentioned, it is always as the mother of Adonijah.
       Immediately after the name of Haggith in I Kings 1:5, is the passage that Adonijah was a man who "exalted himself, saying, I will be king."
       Haggith is mentioned another time when Nathan spoke to Bathsheba, mother of Solomon, saying, "Has thou not heard that Adonijah the son of Haggith doth reign, and David our lord knoweth it not?" 1 Kings 1:11. Solomon took this attempt to be a plot to seize the throne, and because of it Haggith's son, Adonijah, was put to death.
       Finally, in Chronicles the name of "Haggith, mother of Adonijah" is again recorded. Are not the son's selfish attempts to push himself a reflection of the character of his mother, who has no identity except through her son?
