1 Samuel 20:24-29

24So David hid himself in the field: and when the new moon had come, the king sat down to eat food. 25And the king sat upon his seat, as at other times, even upon a seat by the wall: and Jonathan arose, and Abner sat by Saul’s side, and David’s place was empty. 26Nevertheless Saul spoke not any thing that day: for he thought, Something hath befallen him, he is not clean; surely he is not clean. 27And it came to pass on the next day, which was the second day of the month, that David’s place was empty: and Saul said to Jonathan his son, Why cometh not the son of Jesse to eat, neither yesterday, nor to day? 28And Jonathan answered Saul, David earnestly asked leave of me to go to Bethlehem: 29And he said, Let me go, I pray thee; for our family hath a sacrifice in the city; and my brother, he hath commanded me to be there : and now, if I have found favour in thy eyes, let me get away, I pray thee, and see my brethren. Therefore he cometh not to the king’s table.
