1 Samuel 19:23

until he came to Naioth The inspiration seized Saul even before he reached the company of prophets. He was to be convinced of the irresistible might of the Divine Spirit against whose influence he had striven. He was to be taught, if his heart was not already too utterly hardened to learn, that in fighting against David he was fighting against God, and engaging in a futile struggle. For this reason Saul, as the chief agent in David's persecution, was struck down more completely than his servants, and lay there unconscious "all that day and all that night."
