50 Adonijah feared because of Solomon; and he arose, and went, and caught hold on the horns of the altar. 51 It was told Solomon, saying, “Behold, Adonijah fears king Solomon; for, behold, he has laid hold on the horns of the altar, saying, ‘Let king Solomon swear to me first that he will not kill his servant with the sword.’” 52 Solomon said, “If he shows himself a worthy man, there shall not a hair of him fall to the earth; but if wickedness be found in him, he shall die.” 53 So king Solomon sent, and they brought him down from the altar. He came and did obeisance to king Solomon; and Solomon said to him, “Go to your house.”

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.
