'War' in the Bible

I saw, and the same horn made war with the saints, and prevailed against them;

After the sixty-two weeks the Anointed One shall be cut off, and shall have nothing: and the people of the prince who shall come shall destroy the city and the sanctuary; and its end shall be with a flood, and even to the end shall be war; desolations are determined.

His sons shall war, and shall assemble a multitude of great forces, which shall come on, and overflow, and pass through; and they shall return and war, even to his fortress.

He shall stir up his power and his courage against the king of the south with a great army; and the king of the south shall war in battle with an exceeding great and mighty army; but he shall not stand; for they shall devise devices against him.
