1 Samuel 18:13-16

18:13 Saul removed David from his presence and made him a commanding officer. David led the army out to battle and back. 18:14 Now David achieved success in all he did, for the Lord was with him. 18:15 When Saul saw how very successful he was, he was afraid of him. 18:16 But all Israel and Judah loved David, for he was the one leading them out to battle and back.
