What is the Norse Prayer in the 13th warrior?

Its not a prayer found outside of Ibn Fadlan's account of the Rus, but nonetheless, it is an inspiring prayer.

Lo, there do I see my father
Lo, there do I see my mother and my sisters
and my brothers
Lo, there do I see the line of my people back
to the beginning
Lo, they do call to me
They bid me take place among them
in the Halls of Valhalla
Where the brave may live forever...
