'Buckler' in the Bible

Take up the buckler and the shield, and rise up to help me.

"Prepare buckler and shield, and advance into the battle!

I'm going to turn you around, put hooks into your jaws, and bring you out you and your whole army along with your horses and cavalry riders, all of them richly attired, a magnificent company replete with buckler and shield, and all of them wielding battle swords.
