'War' in the Bible

"Then the LORD told me, "Don't harass Moab or provoke them to war, because I won't give you any part of their land. I have given Ar to the descendants of Lot as their property.

When you come to the Ammonites, don't harass or provoke them to war, for I won't give any part of Ammonite land to you, since I have given it to the descendants of Lot as their property.

Get ready and set out for the Wadi Arnon. Look! I've given into your control Sihon the Amorite, king of Heshbon, along with his land. Prepare to take possession by provoking him to war.

"When you go to war against your enemies and observe more horses, chariots, and soldiers than you have, don't be afraid of them, for the LORD your God who brought you out of the land of Egypt is with you.

"When you approach a city to wage war against it, extend terms of peace.

But if they refuse to make peace with you and instead choose war, then attack it.

However, you may cut down the trees whose fruit you know isn't edible, in order to build siege works against the city that waged war with you, until it falls."

"When a man is newly married, he must not be sent out to war or have a related duty placed on him. Let him stay home for one year and be happy with his wife whom he has married.
