'Battles' in the Bible

that we also may be like all the nations, and that our king may judge us, and go out before us, and fight our battles."

Saul said to David, "Behold, my elder daughter Merab, I will give her to you as wife. Only be valiant for me, and fight Yahweh's battles." For Saul said, "Don't let my hand be on him, but let the hand of the Philistines be on him."

Please forgive the trespass of your handmaid. For Yahweh will certainly make my lord a sure house, because my lord fights the battles of Yahweh; and evil shall not be found in you all your days.
