"He shall deathless stand"

This comes from the end of J. R. R. Tolkien's translation of The Lay of the Völsungs, IX.80-81. I wonder how much of this is original to the poem and how much is influenced by Tolkien's own faith. Whatever it is, it's awesome.

In the Day of Doom
he shall deathless stand
who death tasted
and dies no more,
the serpent-slayer,
seed of Ódin:
not all shall end,
nor Earth perish.

On his head the Helm,
in his hand lightning,
afire his spirit,
in his face splendour.
When war passeth
in world rebuilt,
bliss shall they drink
who the bitter tasted.

I really enjoyed the whole poem, both for its deeper glimpse into the Norse mythos and for its rich influence on Tolkien's other work. And it has given me the itch to pick up Niebelungenlied, The Silmarillion and The Children of Húrin again. Go figure.
