It is to to me prins grant desire for becoming pastour,
and for knowing the turn of it. "

" How seroit pastour which does not have nothing has to keep? "
" If avoye vostre love, the saroye to keep well,
because I in scay well the turn. "

" Me love will not arez crumb,
of paour of deshonnour,
jamès day of my life I liked by love,
and if in scay the turn. "

" Friendly, beautiful friend,
craingnés deshonnour,

The beautiful one is soubzrise by saying,
" Friendly doulx, if you know the own way of the pretty set of loves,
if me will monstrez the turn of it. "
