'War' in the Bible

give help! let us act wisely concerning it, lest it multiply, and it hath come to pass, when war happeneth, that it hath been joined, even it, unto those hating us, and hath fought against us, and hath gone out up of the land.'

And it cometh to pass in Pharaoh's sending the people away, that God hath not led them the way of the land of the Philistines, for it is near; for God said, 'Lest the people repent in their seeing war, and have turned back towards Egypt;'

and saith, 'Because a hand is on the throne of Jah, war is to Jehovah with Amalek from generation -- generation.'
