'War' in the Bible

As I kept looking, that horn was making war with the saints (believers) and overpowering them

Then after the sixty-two weeks [of years] the Anointed One will be cut off [and denied His Messianic kingdom] and have nothing [and no one to defend Him], and the people of the [other] prince who is to come will destroy the city and the sanctuary. Its end will come with a flood; even to the end there will be war; desolations are determined.

Also he will carry off to Egypt their [Syrian] gods with their cast images and their precious and costly treasure of silver and of gold, and he will refrain from waging war against the king of the North for some years.

“His sons will prepare for battle and assemble a multitude of great forces; which will keep on coming and overflow [the land], and pass through, so that they may again wage war as far as his fortress.

He will stir up his strength and courage against [his former Egyptian ally] the king of the South (Ptolemy VI) with a great army; so the king of the South will prepare an extremely great and powerful army to wage war, but he will not stand, for schemes will be devised against him.
