31For as long as the son of Jesse lives on this earth, neither you nor your kingship shall be established. Now send for him and bring him to me, for he must surely die!”
32“Why must he be put to death?” Jonathan replied. “What has he done?”
33Then Saul hurled his spear at Jonathan to kill him; so Jonathan knew that his father was determined to kill David.
