1 Samuel 20:31-33

King James Version

³¹ For as long as the son of Jesse liveth upon the ground, thou shalt not be established, nor thy kingdom. Wherefore now send and fetch him unto me, for he shall surely die.

³² And Jonathan answered Saul his father, and said unto him, Wherefore shall he be slain? what hath he done?

³³ And Saul cast a javelin at him to smite him: whereby Jonathan knew that it was determined of his father to slay David.
