1 Samuel 20:25-29

Now the king sat on his seat as usual, the seat by the wall; then Jonathan stood up and Abner sat down by Saul’s side; but David’s place was empty.

Nevertheless Saul did not say anything that day, because he thought, “It must have been an accident; he is not clean, undoubtedly he is not clean.”

But 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?”

And Jonathan answered Saul, “David earnestly requested leave of me to go to Bethlehem.

He 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.” Saul Is Angry with Jonathan
