I Kings 1:50-53

Now Adonijah was afraid of Solomon; so he arose, and went and took hold of the horns of the altar. And it was told Solomon, saying, “Indeed Adonijah is afraid of King Solomon; for look, he has taken hold of the horns of the altar, saying, ‘Let King Solomon swear to me today that he will not put his servant to death with the sword.’ ” Then Solomon said, “If he proves himself a worthy man, not one hair of him shall fall to the earth; but if wickedness is found in him, he shall die.” So King Solomon sent them to bring him down from the altar. And he came and fell down before King Solomon; and Solomon said to him, “Go to your house.”
