Haggith, from a Hebrew name pronounced khag-geeth which means festive (the root word from which khag-geeth is derived means to move in circles i.e. to dance) was one of the wives of King David. Haggith's son was Adonijah, however he was not destined to succeed his father David as king. A number of David's wives, including Haggith, witnessed the death of their royal son. Some of the others were Ahinoam the mother of Amnon (Amnon was put to death by his brother Absalom for assaulting their sister Tamar; see Tamar and Amnon) and Maacah the mother of Absalom (Absalom was killed in battle by David's army commander Joab after Absalom attempted a coup against his father David).
"Adonijah the son of Haggith"
King David started a family, from numerous wives, while in Hebron (see The Hebron Years). Among them was Haggith who gave birth to Adonijah.
"Now there was long war between the house of Saul and the house of David: but David waxed stronger and stronger, and the house of Saul waxed weaker and weaker.
And unto David were sons born in Hebron: and his firstborn was Amnon, of Ahinoam the Jezreelitess; And his second, Chileab, of Abigail the wife of Nabal the Carmelite; and the third, Absalom the son of Maacah the daughter of Talmai king of Geshur; And the fourth, Adonijah the son of Haggith; and the fifth, Shephatiah the son of Abital; And the sixth, Ithream, by Eglah David's wife. These were born to David in Hebron." (2 Samuel 3:1-5 KJV)
Adonijah the son of Haggith was the fourth-born son of David. After the death of his older brothers, Amnon and Absalom, Adonijah assumed himself to the throne. But The Lord had already chosen Solomon, Adonijah's younger brother, to succeed David. Nevertheless, Adonijah had himself proclaimed king while David was even yet living. Nathan and Bathsheba brought the situation to David's attention; David then declared Solomon king, even though David was himself yet alive.
"Now king David was old and stricken in years; and they covered him with clothes, but he gat no heat. Wherefore his servants said unto him, Let there be sought for my lord the king a young virgin: and let her stand before the king, and let her cherish him, and let her lie in thy bosom, that my lord the king may get heat.
So they sought for a fair damsel throughout all the coasts of Israel, and found Abishag a Shunammite, and brought her to the king. And the damsel was very fair, and cherished the king, and ministered to him: but the king knew her not.
Then Adonijah the son of Haggith exalted himself, saying, I will be king: and he prepared him chariots and horsemen, and fifty men to run before him. And his father had not displeased him at any time in saying, Why hast thou done so? and he also was a very goodly man; and his mother bare him after Absalom.
And he conferred with Joab the son of Zeruiah, and with Abiathar the priest: and they following Adonijah helped him. But Zadok the priest, and Benaiah the son of Jehoiada, and Nathan the prophet, and Shimei, and Rei, and the mighty men which belonged to David, were not with Adonijah.
And Adonijah slew sheep and oxen and fat cattle by the stone of Zoheleth, which is by Enrogel, and called all his brethren the king's sons, and all the men of Judah the king's servants: But Nathan the prophet, and Benaiah, and the mighty men, and Solomon his brother, he called not.
Wherefore Nathan spake unto Bathsheba the mother of Solomon, saying, Hast thou not heard that Adonijah the son of Haggith doth reign, and David our lord knoweth it not? Now therefore come, let me, I pray thee, give thee counsel, that thou mayest save thine own life, and the life of thy son Solomon." (1 Kings 1:1-12 KJV)
After his first plot failed, Adonijah then asked Bathsheba to ask Solomon for Abishag in marriage.
"Then sat Solomon upon the throne of David his father; and his kingdom was established greatly.
And Adonijah the son of Haggith came to Bathsheba the mother of Solomon. And she said, Comest thou peaceably?
And he said, Peaceably. He said moreover, I have somewhat to say unto thee.
And she said, Say on.
And he said, Thou knowest that the kingdom was mine, and that all Israel set their faces on me, that I should reign: howbeit the kingdom is turned about, and is become my brother's: for it was his from The Lord. And now I ask one petition of thee, deny me not.
And she said unto him, Say on.
And he said, Speak, I pray thee, unto Solomon the king, for he will not say thee nay, that he give me Abishag the Shunammite to wife." (1 Kings 2:12-17 KJV)
