1 Samuel 20:26-34

That day Saul said nothing. He thought, “Maybe something has happened to David so that he is unclean.” But the next day was the second day of the month, and David’s place was still empty. So Saul said to Jonathan, “Why hasn’t the son of Jesse come to the feast yesterday or today?” Jonathan answered, “David begged me to let him go to Bethlehem. He said, ‘Let me go, because our family has a sacrifice in the town, and my brother has ordered me to be there. Now if I am your friend, please let me go to see my brothers.’ That is why he has not come to the king’s table.” Then Saul became very angry with Jonathan. He said, “You son of a wicked, worthless woman! I know you are on the side of David son of Jesse! You bring shame on yourself and on your mother who gave birth to you. As long as Jesse’s son lives, you will never be king or have a kingdom. Now send for David and bring him to me. He must die!” Jonathan asked his father, “Why should David be killed? What wrong has he done?” Then Saul threw his spear at Jonathan, trying to kill him. So Jonathan knew that his father really wanted to kill David. Jonathan was very angry and left the table. That second day of the month he refused to eat. He was ashamed of his father and upset over David.
