'Men of War' in the Bible

And none of the sons of Israel hath Solomon made servants for his work, but they are men of war, and heads of his captains, and heads of his charioteers, and of his horsemen;

And Abijah directeth the war with a force of mighty men of war, four hundred thousand chosen men, and Jeroboam hath set in array with him battle, with eight hundred thousand chosen men, mighty of valour.

and he hath much work in cities of Judah; and men of war, mighty of valour, are in Jerusalem.
