'Fight' in the Bible

So the Lord our God gave up Og, king of Bashan, and all his people into our hands; and we overcame him so completely that all his people came to their end in the fight.

If you are not able to give a decision as to who is responsible for a death, or who is right in a cause, or who gave the first blow in a fight, and there is a division of opinion about it in your town: then go to the place marked out by the Lord your God;

Give ear, O Israel: today you are going forward to the fight; let your heart be strong; do not let uncontrolled fear overcome you because of those who are against you;

And let the overseers say to the people, If there is any man who has made for himself a new house and has not gone into it, let him go back to his house, so that in the event of his death in the fight, another may not take his house for himself.

Or if any man has made a vine-garden without taking the first-fruits of it, let him go back to his house, so that in the event of his death in the fight, another may not be the first to make use of the fruit.

Or if any man is newly married and has had no sex relations with his wife, let him go back to his house, so that in the event of his death in the fight, another man may not take her.
