An English "gird" means to put a belt around your waist, or something similar, to hold things together. It can also mean to encircle or surround with forces.
When you hear someone say they girded themselves for battle, it's likely that they're talking about putting on armor and getting ready to fight. But "gird" can be used in other ways too - like when a city is girded by a wall to protect its people from invaders.
To bind with a flexible rope or cord.
Example: The fasces were girt about with twine in bundles large.
To jeer at.
