Beowulf: What Is This?

Hwæt, Hrodulf readnosa hrandeor --
Næfde þæt nieten unsciende næsðyrlas!
Glitenode and gladode godlice nosgrisele.
Ða hofberendas mid huscwordum hine gehefigodon;
Nolden þa geneatas Hrodulf næftig
To gomene hraniscum geador ætsomne.
Þa in Cristesmæsseæfne stormigum clommum,
Halga Claus þæt gemunde to him maðelode:
"Neahfreond nihteage nosubeorhtende!
Min hroden hrædwæn gelæd ðu, Hrodulf!"
Ða gelufodon hira laddeor þa lyftflogan --
Wæs glædnes and gliwdream; hornede sum gegieddode
"Hwæt, Hrodulf readnosa hrandeor,
Brad springð þin blæd: breme eart þu!"
