1 Samuel 20:27-29

27And it happened the next day, the second day of the month, that David’s place was empty. And Saul said to Jonathan his son, “Why has the son of Jesse not come to eat, either yesterday or today?”

28So Jonathan answered Saul, “David earnestly asked permission of me to go to Bethlehem.

29And he said, ‘Please let me go, for our family has a sacrifice in the city, and my brother has commanded me to be there. And now, if I have found favor in your eyes, please let me get away and see my brothers.’ Therefore he has not come to the king’s table.”
