'Man of War' in the Bible

The LORD is a man of war, Jehovah is his name:

And the tribe of Manasseh which was the eldest son of Joseph received a lot. And Machir, the eldest son of Manasseh, which was the father of Gilead and a man of war, had Gilead and Bashan.

Then answered one of his servants and said, "Behold, I have seen a son of Jesse the Bethlehemite, that can play upon instruments, and is an active fellow and a man of war and prudent and well made, and the LORD is with him."

And Saul said to David again, "Thou art not able to go unto this Philistine, to fight with him. For thou art but a lad, and he hath been a man of war even from his youth."

But God said to me, 'Thou shalt not build a house for my name, because thou art a man of war and hast shed blood.'

The LORD shall come forth as a giant, and take a stomach to himself like a fresh man of war. He shall roar and cry, and overcome his enemies.
