'War' in the Bible

He will judge between the nations, and will decide concerning many peoples; and they shall beat their swords into plowshares, and their spears into pruning hooks. Nation shall not lift up sword against nation, neither shall they learn war any more.

the mighty man, the man of war, the judge, the prophet, the diviner, the elder,

Your men shall fall by the sword, and your mighty in the war.

It happened in the days of Ahaz the son of Jotham, the son of Uzziah, king of Judah, that Rezin the king of Syria, and Pekah the son of Remaliah, king of Israel, went up to Jerusalem to war against it, but could not prevail against it.

I say that your counsel and strength for the war are only vain words. Now in whom do you trust, that you have rebelled against me?

You will seek them, and won't find them, even those who contend with you. Those who war against you will be as nothing, as a non-existent thing.

Yahweh will go out like a mighty man. He will stir up zeal like a man of war. He will raise a war cry. Yes, he will shout aloud. He will triumph over his enemies.
