Arm can be defined as "power, might, strength, and authority." However, it can also be defined as "a weapon" or "to provide whatever will add strength, force, or security."

This idea echoes through the battle between Grendel and Beowulf when the sword fails Beowulf and his followers: "All of Beowulf's band had jumped from their beds, ancestral swords raised and ready, determined to protect their prince if they could. Their courage was
