A sample of Old English:
Fder ūre, ū ē eart on heofonum,
Sī īn nama gehālgod.
Tō becume īn rice.
Gewurde īn willa
On eoran swā swā on heofonum.
Urne gedgwhamlīcan hlāf syle ūs tōdg.
And forgyf ūs ūre gyltas,
Swā swā wē forgyfa ūrum gyltendum.
And ne geld ū ūs on costnunge,
ac alȳs ūs of yfele.

Early Modern, about the time of the KJV:
Our Father, which art in heaven,
hallowed be thy name;
thy kingdom come;
thy will be done,
in earth as it is in heaven.
Give us this day our daily bread.
And forgive us our trespasses,
as we forgive them that trespass against us.
And lead us not into temptation;
but deliver us from evil.
