1 Samuel 20:24-34

So David hid in the field; and when the New Moon [festival] came, the king sat down to eat food. The king sat on his seat as on previous occasions, on his seat by the wall; then Jonathan stood up, and Abner [his commander] sat down by Saul’s side, but David’s place was empty. Yet Saul did not say anything that day, for he thought, “It is an incident [of some kind] and he is not [ceremonially] clean—surely he is unclean.” But on the next day, the second day of the new moon, David’s place was empty [again]; and Saul said to Jonathan his son, “Why has the son of Jesse not come to the meal, either yesterday or today?” Jonathan answered Saul, “David earnestly asked me for permission to go to Bethlehem. He said, ‘Please let me go because our family is holding a sacrifice in the city, and my brother has commanded me to attend. Now, if I have found favor in your eyes, please let me slip away so that I may see my brothers.’ That is why he has not come to the king’s table.” Then Saul’s anger burned against Jonathan and he said to him, “You son of a wayward, rebellious woman! Do I not know that you have chosen the son of Jesse [over me] to your own shame, and to the shame of your mother’s nakedness? For as long as the son of Jesse lives on the earth, neither you [as heir to the throne] nor your kingdom will be established. So now, send [someone] and bring him to me, for he must die.” Jonathan answered Saul his father, “Why must he be put to death? What has he done?” Then Saul hurled his spear at him to strike him down, so Jonathan knew [without any doubt] that his father had decided to put David to death. Then Jonathan stood up from the table in the heat of anger, and ate no food on that second day of the new moon (month), for he grieved and worried about David because his father had dishonored him.
