1 Samuel 20:24-26

David hid in the field. On the holiday of the New Moon, the king came to the table to eat. He sat where he always sat, the place against the wall, with Jonathan across the table and Abner at Saul’s side. But David’s seat was empty. Saul didn’t mention it at the time, thinking, “Something’s happened that’s made him unclean. That’s it—he’s probably unclean for the holy meal.”
