1 Samuel 18:28-32

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

then Saul was even more afraid of David. So Saul was David’s enemy continually.

Then the commanders of the Philistines went to battle, and it happened as often as they went out, that David was more successful than all the servants of Saul. So his name was held in high esteem.
