1 Samuel 20:24-27

24So David hid in the field, and when the New Moon feast came, the king sat down to eat. 25He sat in his customary place by the wall, opposite Jonathan, Septuagint; Hebrew wall. Jonathan arose and Abner sat next to Saul, but David’s place was empty. 26Saul said nothing that day, for he thought, “Something must have happened to David to make him ceremonially unclean—surely he is unclean.”

27But the next day, the second day of the month, David’s place was empty again. Then Saul said to his son Jonathan, “Why hasn’t the son of Jesse come to the meal, either yesterday or today?”
