Guiler

And þow hast gyuen hire to a gyloure · now god gyf þe sorwe.

But he was wary wise in all his way, And well perceived his deceitful sleight, Ne suffered Lust his Safety to betray; So goodly did beguile the Guiler of the Prey

The devil is the arch-trickster — who tricked Man with the apple in Eden — and in the 'guiler beguiled' model God beats him at his own game with the ultimate 'trick', or paradox of the God–man Jesus.
