'War' in the Bible

I kept looking, and that horn was waging war with the saints and overpowering them

Then after the sixty-two weeks the Messiah will be cut off and have nothing, and the people of the prince who is to come will destroy the city and the sanctuary. And its end will come with a flood; even to the end there will be war; desolations are determined.

“His sons will mobilize and assemble a multitude of great forces; and one of them will keep on coming and overflow and pass through, that he may again wage war up to his very fortress.

He will stir up his strength and courage against the king of the South with a large army; so the king of the South will mobilize an extremely large and mighty army for war; but he will not stand, for schemes will be devised against him.
