1 Kings 1:53

So King Solomon sent, and they brought him down from the altar. "Solomon regarded Adonijah's flight to the horns of the altar as a confession of his guilt and repentance, and he exercised an act of clemency which could only produce the most favorable impression upon the people. " (Lange.) And he came and bowed himself to King Solomon, acknowledging him as rightful king; and Solomon said unto him, Go to thine house. He was granted life and freedom. Note: All those who have left the kingdom of Christ, but return to Him while the-time of grace is still upon them, will not be cast out by Him; for with Him there is mercy and forgiveness.
