Accused though I be without desert

Accused though I be without desert,
Sith none can prove, beleve it not for true :
For never yet, since that you had my hert.
Intended I to false or be untrue.

Sooner I would of death sustayn the smart
Than break one word of that I promised you :
Accept therfore my service in good part;
None is alyve that can yll tonges eschew ;

Hold them as false, and let not us depart
Our frendship olde, in hope of any new.
Put not thy trust in such as use to fayn,
Except thou mynde to put thy frend to payn.
