1 Samuel 20:28-33

Jonathan answered, “David earnestly asked me for permission to go to Bethlehem. He said, ‘Let me go, because our family is observing a sacrifice in the town and my brother has ordered me to be there. If I have found favor in your eyes, let me get away to see my brothers.’ That is why he has not come to the king’s table.” Saul’s anger flared up at Jonathan and he said to him, “You son of a perverse and rebellious woman! Don’t I know that you have sided with the son of Jesse to your own shame and to the shame of the mother who bore you? As long as the son of Jesse lives on this earth, neither you nor your kingdom will be established. Now send someone to bring him to me, for he must die!” “Why should he be put to death? What has he done?” Jonathan asked his father. But Saul hurled his spear at him to kill him. Then Jonathan knew that his father intended to kill David.
