And Saul said to David, Behold my elder daughter Merab, her will I give thee to wife: only be thou valiant for me, and fight the LORD'S battles. For Saul said, Let not mine hand be upon him, but let the hand of the Philistines be upon him. Fight the Lord's battles - Mr. Calmet properly remarks that the wars of the Hebrews, while conducted by the express orders of God, were truly the wars of the Lord; but when the spirit of worldly ambition and domination became mingled with them, they were no longer the wars of the Lord, but wars of lust and profanity.
