1 Kings 1:50-53

But Adonijah, in fear of Solomon, went and took hold of the horns of the altar. Then Solomon was told, ‘Adonijah is afraid of King Solomon and is clinging to the horns of the altar. He says, “Let King Solomon swear to me today that he will not put his servant to death with the sword.” ’ Solomon replied, ‘If he shows himself to be worthy, not a hair of his head will fall to the ground; but if evil is found in him, he will die.’ Then King Solomon sent men, and they brought him down from the altar. And Adonijah came and bowed down to King Solomon, and Solomon said, ‘Go to your home.’
