[Edit: Ring can be found here.]
Our Sauron who art in Mordor,
accursed be thy name.
Thy kingdom come.
Thy will be done
on Middle-Earth as it is in Barad-Dûr.
Give us this day our daily Lembas bread,
and punish us our trespasses,
as we slay those who trespass against us,
and lead us into temptation of the Ring,
but deliver us unto evil.
For thine are the kingdoms of Arda,
and the power, and the glory,
for ever and ever.
