One man named Unferth was jealous of Beowulf. Thus, he confronted Beowulf for being arrogant., bringing up a battle involving Beowulf and a sea monster called Breca.
1) Aren't you the Beowulf who swam out to sea to battle Breca, just to prove you could win?
2) It was me though, who pierced the monster with my sword. If you were so brave and fierce Unferth, Grendel wouldn't still be killing people. I'll prove to him the power of Geats, and then in morning no one will be afraid to enter Heorot.
Everyone was happier after Beowulf's speach. They knew help had truely arrived. The King's wife, Wealhtheow, entered Heorot and welcomed the guests. She gave Hrothgar, and then Beowulf, another drink, thanking the lord that they finally had a hero.
Night fell. Hrothgar left, knowing that Heorot was safe because God had sent Beowulf there to protect it. There was no one Hrothgar trusted more for the job. Before settling in for the night, Beowulf spoke to his men.
I consider myself as fierce as Grendel, and since he relies on his strength and does not use a sword, I will do the same. If he comes, we will battle, and God shall decide who will win.
From the moorlands, Grendel came. It wasn't the first time he had come to Heorot, but he'd never faced such powerful enemies.
Grendel tore open the door and strode in, eyes aflame with rage. He saw the Geats asleep on the floor and laughed to himself. He planned to kill and eat all of them before morning. However, Beowulf was watching, waiting for him to attack.
Grendel grabbed a warrior right away, ripped him apart and ate him. He turned towards Beowulf and raised his claw to strike.
