'War' in the Bible

As I was watching, this horn waged war against the holy ones and was prevailing over them

After those 62 weeksthe Messiah will be cut offand will have nothing.The people of the coming princewill destroy the city and the sanctuary.The end will come with a flood,and until the end there will be war;desolations are decreed.

“His sons will mobilize for war and assemble a large number of armed forces. They will advance, sweeping through like a flood, and will again wage war as far as his fortress.
