'Battles' in the Bible

And Saul said to David, Behold my eldest daughter Merab, her will I give thee to wife; only be thou valiant for me, and fight Jehovah's battles. But Saul thought, My hand shall not be upon him, but the hand of the Philistines shall be upon him.

I pray thee, forgive the transgression of thy handmaid: for Jehovah will certainly make my lord a lasting house; because my lord fights the battles of Jehovah, and evil has not been found in thee all thy days.

with him is an arm of flesh, but with us is Jehovah our God to help us and to fight our battles. And the people depended upon the words of Hezekiah king of Judah.

And wherever shall pass the appointed staff, which Jehovah shall lay upon him, it shall be with tambours and harps; and with tumultuous battles will he fight with it.
