1 Kings 1:51-52

51It was reported to Solomon, “Look, Adonijah fears King Solomon, and he has taken hold of the horns of the altar, saying, ‘Let King Solomon first swear to me that he will not kill his servant with the sword.’”

52Then Solomon said, “If he is a man of character, not a single hair of his will fall to the ground, but if evil is found in him, he dies.”
