1 Samuel 20:24-29

24So David hid himself in the field. And when the new moon came, the king sat down to eat food.

25The king sat on his seat, as at other times, on the seat by the wall. Jonathan sat opposite, and Abner sat by Saul's side, but David's place was empty.

26Yet Saul did not say anything that day, for he thought, "Something has happened to him. He is not clean; surely he is not clean."

27But on the second day, the day after the new moon, David's place was empty. And Saul said to Jonathan his son, "Why has not the son of Jesse come to the meal, either yesterday or today?"

28Jonathan answered Saul, "David earnestly asked leave of me to go to Bethlehem.

29He said, 'Let me go, for our clan holds a sacrifice in the city, and my brother has commanded me to be there. So now, if I have found favor in your eyes, let me get away and see my brothers.' For this reason he has not come to the king's table."
