1 Kings 1:49-51

49 And all the guests that were with Adoniyah were terrified, and rose up, and went, every man, on his own way.

50 And Adoniyah was afraid because of Solomon; and he arose, and went, and caught hold on the horns of the altar.

51 And it was told unto Solomon, saying, Behold, Adoniyah feareth king Solomon; and, behold, he hath caught hold on the horns of the altar, saying, Let king Solomon swear unto me today that he will not slay his servant with the sword.
