Saxon Riddle

This Saxon riddle can be found in the extent Exeter Book,
placed in Exeter Cathedral by its first Bishop, Leofric, in 1072.

On Earth there is a warrior of curious origin.
He's created gleaming by two dumb creatures for the benefit of men.
Foe bears him against foe to inflict harm.
Women often fetter him, strong as he is.
If maidens and men care for him,
with due consideration and feed him frequently,
he'll faithfully obey them
and serve them well.
Men succour him for the warmth
he offers in return; but this worior will savage
anyone who permits him to become too proud.
