1 Samuel 18:28-30

28When Saul saw and realized that Adonai was with David and that Michal, Saul’s daughter, loved him,

29Saul grew even more afraid of David. Thus Saul became David’s enemy for all days.

30When the chiefs of the Philistines marched out, as often as they came out, David proved more successful than all of Saul’s officers. So his name became highly esteemed.
