1 Samuel 20:27-29

27But on the next day, the second day of the new moon, David’s place was empty [again]; and Saul said to Jonathan his son, “Why has the son of Jesse not come to the meal, either yesterday or today?”

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

29He said, ‘Please let me go because our family is holding a sacrifice in the city, and my brother has commanded me to attend. Now, if I have found favor in your eyes, please let me slip away so that I may see my brothers.’ That is why he has not come to the king’s table.”
