1 Kings 1:50-53

50Adonijah was afraid of Solomon, so he rushed to the sacred tent and grabbed on to the horns of the altar.

51Word soon reached Solomon that Adonijah had seized the horns of the altar in fear, and that he was pleading, “Let King Solomon swear today that he will not kill me!”

52Solomon replied, “If he proves himself to be loyal, not a hair on his head will be touched. But if he makes trouble, he will die.”

53So King Solomon summoned Adonijah, and they brought him down from the altar. He came and bowed respectfully before King Solomon, who dismissed him, saying, “Go on home.”
