'Fight' in the Bible

and they conspired all of them together to come and fight against Jerusalem, and to cause confusion therein.

And I looked, and rose up, and said unto the nobles, and to the rulers, and to the rest of the people, Be not ye afraid of them: remember the Lord, who is great and terrible, and fight for your brethren, your sons, and your daughters, your wives, and your houses.

in what place soever ye hear the sound of the trumpet, resort ye thither unto us; our God will fight for us.
