Beowulf tells Hrothgar that he will fight Grendel with his bare hands, as Grendel doesn't fight with weapons (it seems he can't even be killed with a blade). The only help Beowulf will get is the help of his warriors. Beowulf is aware that the lives of all his warriors are at stake, and anticipates that Grendel will eat them if they fail, but he is still eager to do this. This reveals that the leader is always the first one to fight, in front of his followers. But although he vouches for their lives, they must follow him to death, if need be.
Just like Beowulf is a leader to his warriors, Hrothgar, as a king, is the spiritual leader of the realm. Beowulf yields to him and wants to fight and even die for him, as Hrothgar represents the God's will on Earth. When the realm is physically endangered by a murderous, devilish villain, it means that the God's order on Earth is symbolically endangered, and it takes a hero to restore it.
There are lots of reasons why people read. You may simply want to relax, after a long day, I find it quite relaxing to just chill and read for a couple of hours. You can do specific reading, in order to bolster your understanding on a specific subject. We can also boost our vocabulary when reading, we learn new words constantly. You can train your brain, because you need to visualize a whole world while reading. Some people read because it makes them feel good. All in all, books open up a whole new world to the reader, and have many benefits, I've only listed some, and I hope this helps you!
Wind is often used for directional and navigational purposes, so this could mean that the author followed something by the wind whether it be how high or low the air- pressure is or which way the wind is blowing. Aswell as the fact that Wind is a major factor in weather determination. For example, if the wind blows ina counter- clockwise direction, then the air pressure is low which means that the weather is or will be bad like rain or storms.
Hope this helps!
