'War' in the Bible

I beheld, and that horn made war with the saints, and prevailed over them;

And after the sixty-two weeks shall Messiah be cut off, and shall have nothing; and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with an overflow, and unto the end, war, the desolations determined.

And his sons shall be stirred up, and shall assemble a multitude of great forces; and one shall certainly come, and overflow, and pass through; and he shall return and carry the war even to his fortress.
