Saul knew that the Lord was with David He was convinced of it, by the success which he constantly had in all his undertakings. And Saul was yet the more afraid of David Having thus advanced him; and seeing no hope of bringing his designs to pass against him. And Saul became David's enemy continually He was every day more resolved to destroy him. Such strange blindness did his anger and hatred, and such like passions, bring upon him, that he set himself against him, who he saw and knew, had God for his friend! In what a lost condition must Saul's mind have now been!
