1 Samuel 18:28-30

28 ¶ And Saul saw and knew that the Lord was with David, and that Michal Saul’s daughter loved him. 29 And Saul was yet the more afraid of David; and Saul became David’s enemy continually. 30 Then the princes of the Philistines went forth: and it came to pass, after they went forth, that David behaved himself more wisely than all the servants of Saul; so that his name was much set by.
