1 Kings 1:38-2:4

So Zadok the priest, Nathan the prophet, and Benai'ah the son of Jehoi'ada, and the Cher'ethites and the Pel'ethites, went down and caused Solomon to ride on King David's mule, and brought him to Gihon. There Zadok the priest took the horn of oil from the tent, and anointed Solomon. Then they blew the trumpet; and all the people said, "Long live King Solomon!" And all the people went up after him, playing on pipes, and rejoicing with great joy, so that the earth was split by their noise. Adoni'jah and all the guests who were with him heard it as they finished feasting. And when Jo'ab heard the sound of the trumpet, he said, "What does this uproar in the city mean?" While he was still speaking, behold, Jonathan the son of Abi'athar the priest came; and Adoni'jah said, "Come in, for you are a worthy man and bring good news." Jonathan answered Adoni'jah, "No, for our lord King David has made Solomon king; and the king has sent with him Zadok the priest, Nathan the prophet, and Benai'ah the son of Jehoi'ada, and the Cher'ethites and the Pel'ethites; and they have caused him to ride on the king's mule; and Zadok the priest and Nathan the prophet have anointed him king at Gihon; and they have gone up from there rejoicing, so that the city is in an uproar. This is the noise that you have heard. Solomon sits upon the royal throne. Moreover the king's servants came to congratulate our lord King David, saying, 'Your God make the name of Solomon more famous than yours, and make his throne greater than your throne.' And the king bowed himself upon the bed. And the king also said, 'Blessed be the LORD, the God of Israel, who has granted one of my offspring to sit on my throne this day, my own eyes seeing it.'" Then all the guests of Adoni'jah trembled, and rose, and each went his own way. And Adoni'jah feared Solomon; and he arose, and went, and caught hold of the horns of the altar. And it was told Solomon, "Behold, Adoni'jah fears King Solomon; for, lo, he has laid hold of the horns of the altar, saying, 'Let King Solomon swear to me first that he will not slay his servant with the sword.'" And Solomon said, "If he prove to be a worthy man, not one of his hairs shall fall to the earth; but if wickedness is found in him, he shall die." So King Solomon sent, and they brought him down from the altar. And he came and did obeisance to King Solomon; and Solomon said to him, "Go to your house." When David's time to die drew near, he charged Solomon his son, saying, "I am about to go the way of all the earth. Be strong, and show yourself a man, and keep the charge of the LORD your God, walking in his ways and keeping his statutes, his commandments, his ordinances, and his testimonies, as it is written in the law of Moses, that you may prosper in all that you do and wherever you turn; that the LORD may establish his word which he spoke concerning me, saying, 'If your sons take heed to their way, to walk before me in faithfulness with all their heart and with all their soul, there shall not fail you a man on the throne of Israel.'
