1 Samuel 20:27-29
20:27 But the next morning, the second day of the new moon, David’s place was still vacant. So Saul said to his son Jonathan, “Why has Jesse’s son not come to the meal yesterday or today?”
20:28 Jonathan replied to Saul, “David urgently requested that he be allowed to go to Bethlehem.
20:29 He said, ‘Permit me to go, for we are having a family sacrifice in the city, and my brother urged me to be there. So now, if I have found favor with you, let me go to see my brothers.’ For that reason he has not come to the king’s table.”
