1 Samuel 20:23-33

23 As for what you and I were talking of, the Lord is between you and me for ever.
24 So David went to a secret place in the country: and when the new moon came, the king took his place at the feast.
25 And the king took his seat, as at other times, by the wall: and Jonathan was in front, and Abner was seated by Saul's side, but there was no one in David's seat.
26 But Saul said nothing that day, for his thought was, Something has taken place making him unclean; it is clear that he is not clean.
27 And on the day after the new moon, that is, the second day, there was still no one in David's seat: and Saul said to his son Jonathan, Why has the son of Jesse not come to the feast yesterday or today?
28 And answering Saul, Jonathan said, He made a request to me that he might go to Beth-lehem,
29 Saying, Our family is making an offering in the town, and my brothers have given me orders to be there: so now, if I have grace in your eyes, let me go away and see my brothers. This is why he has not come to the king's table.
30 Then Saul was moved to wrath against Jonathan, and he said to him, You son of an evil and uncontrolled woman, have I not seen how you have given your love to the son of Jesse, to your shame and the shame of your mother?
31 For while the son of Jesse is living on the earth, your position is unsafe and your kingdom is in danger. So make him come here to me, for it is certainly right for him to be put to death.
32 And Jonathan, answering his father Saul, said to him, Why is he to be put to death? What has he done?
33 And Saul, pointing his spear at him, made an attempt to give him a wound: from which it was clear to Jonathan that his father's purpose was to put David to death.
