warrior passages from religious books

I'm looking for excerpts from the Bible, the Koran and the Torah that are about preparing for battle. I'd like as little religious stuff as possible within the passage, less "We fight for God" and more "Fill your heart with bravery and stand tall in the face of evil".

The only thing I've managed to find so far is Ephesians 6:10-20.

Other, non-religious inspirational quotes are welcome too.

Ask you local EXPERT THEOLOGIAN

I am the bone of my sword,
Steel is my Body and Fire is my Blood.
I have created over a Thousand Blades,
Unknown to Death,
Nor known to Life.
Have withstood Pain to create many Weapons
Yet those Hands will never hold Anything.
So, as I Pray--
Unlimited Blade Works

Psalm 18:37 and on was in large part our Company quote when I served in the West Bank.
