2 Samuel 3:4

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. Go and get thee in unto king David, and say unto him, Didst not thou, my lord, O king, swear unto thine handmaid, saying, Assuredly Solomon thy son shall reign after me, and he shall sit upon my throne? why then doth Adonijah reign? Behold, while thou yet talkest there with the king, I also will come in after thee, and confirm thy words. And Bathsheba went in unto the king into the chamber: and the king was very old; and Abishag the Shunammite ministered unto the king. And Bathsheba bowed, and did obeisance unto the king. And the king said, What wouldest thou? And she said unto him, My lord, thou swarest by the LORD thy God unto thine handmaid, saying, Assuredly Solomon thy son shall reign after me, and he shall sit upon my throne. And now, behold, Adonijah reigneth; and now, my lord the king, thou knowest it not:

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. And Bathsheba said, Well; I will speak for thee unto the king. Bathsheba therefore went unto king Solomon, to speak unto him for Adonijah. And the king rose up to meet her, and bowed himself unto her, and sat down on his throne, and caused a seat to be set for the king's mother; and she sat on his right hand. Then she said, I desire one small petition of thee; I pray thee, say me not nay. And the king said unto her, Ask on, my mother: for I will not say thee nay. And she said, Let Abishag the Shunammite be given to Adonijah thy brother to wife. And king Solomon answered and said unto his mother, And why dost thou ask Abishag the Shunammite for Adonijah? ask for him the kingdom also; for he is mine elder brother; even for him, and for Abiathar the priest, and for Joab the son of Zeruiah. Then king Solomon sware by the LORD, saying, God do so to me, and more also, if Adonijah have not spoken this word against his own life. Now therefore, as the LORD liveth, which hath established me, and set me on the throne of David my father, and who hath made me an house, as he promised, Adonijah shall be put to death this day. And king Solomon sent by the hand of Benaiah the son of Jehoiada; and he fell upon him that he died.
