14. Who or what does Sir Gawain initially blame for his failure, citing the events that happened to Adam, Solomon, and Samson in the Bible?

Gawain blames his host's wife, and her feminine wiles.

But no marvel it is if mad be a fool,
and by the wiles of woman to woe be brought.
For even so Adam by one on earth was beguiled,
and Solomon by several, and to Samson moreover
his doom by Delilah was dealt; and David was after
blinded by Bathsheba, and he bitterly suffered.
