I Samuel 18:12-16

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