Beowulf pg 21-57

Pg. 27 (372): I used to know him when he was a young boy. - Hrothgar is saying how he knew Beowulf's father when he was a child and this is a foreshadow that Beowulf's father's good reputation is going to help him. The people back in that time period believed that the morals and values of the father would pass on to further generations. This idea foreshadows that since Beowulf's father is well known he will soon make a good name for himself and take after his father.

Pg. 27 (380-381): With the strength of thirty in the grip of each hand - This suggests that Beowulf is equivalent or stronger than Grendel. This can be assumed because earlier (pg. 11: 22) Grendel was able to grab thirty men in one hand and kill them.

Pg. 33 (471-473): Finally I healed the feud by paying: I shipped a treasure-trove to the Wulfing and Ecgtheow acknowledged me with oaths of allegiance. - Hrothgar payed Beowulf's father's wergild for him when he killed Heatholaf, a Wulfing, and was forced to leave so he went to the South-Danes. This suggests that Hrothgar is a good king and shares his treasures with people. This can also suggest that Beowulf's father did not have a lot of riches and caused a feud.

Pg. 41 (583-586): I don't boast when I say that neither you nor Breca were ever much celebrated for swordship or facing danger on the field of battle. - Unferth is a foil to Beowulf. Rather than heroism Unferth reveals pride and resentment. This also shows that Unferth is not a good warrior because he is a coward, unable to protect Heorot and defeat Grendel himself, and he is also envious of Beowulf because of the reason that he can protect Herot when he doesn't even live there but Unferth is to scared and incapable to do it.

Pg. 53 (794-797): Time and again, Beowulf's warriors worked to defend their lord's life, laying about them as best they could with their ancestral blades. - This statement is parallel to the end and states that Beowulf's warriors are by his side and defending him until the end. It also states how they are very skilled and worshiped warriors because they have swords that have been passed down to them.
