'War' in the Bible

When they finish their testimony, the beast that comes up out of the abyss will make war with them, conquer them, and kill them.

Then war broke out in heaven: Michael and his angels fought against the dragon. The dragon and his angels also fought,

So the dragon was furious with the woman and left to wage war against the rest of her offspring—those who keep God’s commands and have the testimony about Jesus.

They worshiped the dragon because he gave authority to the beast. And they worshiped the beast, saying, “Who is like the beast? Who is able to wage war against him?”

And he was permitted to wage war against the saints and to conquer them. He was also given authority over every tribe, people, language, and nation.

These will make war against the Lamb, but the Lamb will conquer them because He is Lord of lords and King of kings. Those with Him are called, chosen, and faithful.”

Then I saw heaven opened, and there was a white horse. Its rider is called Faithful and True, and He judges and makes war in righteousness.

Then I saw the beast, the kings of the earth, and their armies gathered together to wage war against the rider on the horse and against His army.
