'Fight' in the Bible

come, let us deal wisely with them, lest they multiply, and it come to pass, that, when there falleth out any war, they also join themselves unto our enemies, and fight against us, and get them up out of the land.

Jehovah will fight for you, and ye shall hold your peace.

And Moses said unto Joshua, Choose us out men, and go out, fight with Amalek: to-morrow I will stand on the top of the hill with the rod of God in my hand.
