1 Samuel 20

16 Now when his father had heard these words, he was angry with him, and he drew his sword that he might smite him to the earth.

17 But Ammon stood forth and said unto him: Behold, thou shalt not slay thy son; nevertheless, it were better that he should fall than thee, for behold, he has repented of his sins; but if thou shouldst fall at this time, in thine anger, thy soul could not be saved.
