1 Samuel 18:12-16, 28-30

And Saul was afraid of David, because Jehovah was with him, and was departed from Saul. Therefore Saul removed him from him, and made him his captain over a thousand; and he went out and came in before the people. And David behaved himself wisely in all his ways; and Jehovah was with him. And when Saul saw that he behaved himself very wisely, he stood in awe of him. But all Israel and Judah loved David; for he went out and came in before them.

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