'Warfare' in the Bible

All of them are skilled with a sword, well-trained in the art of warfare. Each has his sword at his side, to guard against the terrors of the night.

"Speak kindly to Jerusalem, and tell her that her time of warfare is over, that her punishment is completed. For the Lord has made her pay double for all her sins."

The Lord is like a lion who has left his lair. So their lands will certainly be laid waste by the warfare of the oppressive nation and by the fierce anger of the Lord."

"At that time I will make a covenant for them with the wild animals, the birds of the air, and the creatures that crawl on the ground. I will abolish the warrior's bow and sword -- that is, every weapon of warfare -- from the land, and I will allow them to live securely."
