Now I cannot recall
any fight you entered, Unferth,
that bears comparison…
You killed your own kith and kin,
so for all your cleverness and quick tongue,
you will suffer damnation in the depths of hell.

Beowulf, Seamus Heaney (trans.)

Lines 582-590: Beowulf challenges the cowardly Unferth who is afraid to stand up for his lord against Grendel.
