1 Samuel 18:12-17

12And Saul was afraid of David, because the LORD was with him, and had departed from Saul. 13Therefore Saul removed him from him, and made him his captain over a thousand; and he went out and came in before the people. 14And David behaved himself wisely in all his ways; and the LORD was with him.1 15Therefore when Saul saw that he behaved himself very wisely, he was afraid of him. 16But all Israel and Judah loved David, because he went out and came in before them. 17And Saul said to David, Behold my elder daughter Merab, her will I give thee for a wife: only be thou valiant for me, and fight the LORD’S battles. For Saul said, Let not my hand be upon him, but let the hand of the Philistines be upon him.2
