1 Kings 1:50-53

50And Adonijah feared because of Solomon; and he arose, and went, and caught hold on the horns of the altar. 51And it was told Solomon, saying, Behold, Adonijah feareth king Solomon; for, lo, he hath laid hold on the horns of the altar, saying, Let king Solomon swear unto me first that he will not slay his servant with the sword. 52And Solomon said, If he shall show himself a worthy man, there shall not a hair of him fall to the earth; but if wickedness be found in him, he shall die. 53So king Solomon sent, and they brought him down from the altar. And he came and did obeisance to king Solomon; and Solomon said unto him, Go to thy house.
