50 Adonijah was afraid of Solomon, so he rushed to the sacred tent and grabbed on to the horns of the altar. 51 Word soon reached Solomon that Adonijah had seized the horns of the altar in fear, and that he was pleading, "Let King Solomon swear today that he will not kill me!" 52 Solomon replied, "If he proves himself to be loyal, not a hair on his head will be touched. But if he makes trouble, he will die." 53 So King Solomon summoned Adonijah, and they brought him down from the altar. He came and bowed respectfully before King Solomon, who dismissed him, saying, "Go on home."

Commentary on 1 Kings 1:32-53
(Read 1 Kings 1:32-53)
The people expressed great joy and satisfaction in the elevation of Solomon. Every true Israelite rejoices in the exaltation of the Son of David. Combinations formed upon evil principles will soon be dissolved, when self-interest calls another way. How can those who do evil deeds expect to have good tidings? Adonijah had despised Solomon, but soon dreaded him. We see here, as in a glass, Jesus, the Son of David and the Son of God, exalted to the throne of glory, notwithstanding all his enemies. His kingdom is far greater than that of his father David, and therein all the true people of God cordially rejoice. The prosperity of his cause is vexation and terror to his enemies. No horns of the altar, nor forms of godliness, nor pretences to religion, can profit those who will not submit to His authority, and accept of his salvation; and if their submission be hypocritical, they shall perish without remedy.
