1 Samuel 20:27-29

27But it came about the next day, the second day of the new moon, that David’s place was empty again; so Saul said to his son Jonathan, “Why has the son of Jesse not come to the meal, either yesterday or today?” 28And Jonathan answered Saul, “1David earnestly requested leave of me to go to Bethlehem. 29He said, ‘Please let me go, because our family has a sacrifice in the city, and my brother has ordered me to attend. So now, if I have found favor in your sight, please let me slip away so that I may see my brothers.’ For this reason he has not come to the king’s table.”
