Here is a literal translation of the Lord's Prayer as it is prayed in Koine. This is my own translation, so don't take it as Gospel (excuse the pun).
Perhaps others may like to critique, correct, add or subtract from it.
The One Who is in the Heavens (plural),
May Thy Name be hallowed,
May Thy Kingdom come,
May Thy Will be done as in Heaven (singular), so on Earth.
The bread of our subsistence, give us today,
And lay aside (remit) us our indebtednesses
As we remit the ones indebted to us
And do not lead us into trial (discipline by provocation)
But release us from the evil one.
