1 Samuel 20:28-29

And Jonathan answered Saul, David earnestly asked leave of me to go to Beth-lehem: and 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 thine eyes, let me get away, I pray thee, and see my brethren. Therefore he cometh not unto the king's table.
