What examples of foreshadowing can be found in the story?

There is the funeral of Shield Sheafson. This is when the poem opens. This foreshadows Beowulf’s funeral at the poem’s end.

-The story of Sigemund told by the scop, or bard, foreshadows Beowulf’s fight with the dragon.

-The story of King Heremod foreshadows Beowulf’s eventual ascendancy to kingship.

I think foreshadowing was used in Anglo-Saxon literature except, from what I can think of right now, it was more subtle and open ended than it is in more contemporary literature.
