Sir Gawain and the Green Knight (Burton Raffel, trans.)

An honest man
Need never fear.
But still, the third day, there
In my castle, you failed - and you felt that here.
'That belt you're wearing: it's mine, my wife
Gave it to you - I know it all, knight,
The kisses you took, and gave, and all
You did, and how she tempted you: everything.
For I planned it all, to test you - and truly,
Not many better men have walked
This earth, been worth as much - like a pearl
To a pea, compared to other knights.
But you failed a little, lost good faith -
Not for a beautiful belt, or in lust,
But for love of your life. I can hardly blame you.'

Part 4, lines 2343-2368
