1 Kings 1:51-52

51Now it was reported to Solomon, saying, “Behold, Adonijah is afraid of King Solomon, for behold, he has taken hold of the horns of the altar, saying, ‘May King Solomon swear to me today that he will not put his servant to death with the sword.’”

52And Solomon said, “If he is a worthy man, 1not one of his hairs will fall to the ground; but if wickedness is found in him, he will die.”
