Be off, Satan, from this floor and from these four walls. This is no place for you; there is nothing for you to do here. This is the place for Peter and Paul and the holy Gospel; and this is where I mean to sleep now that my worship is done, in the name of the Father and of the Holy Spirit.
In the name of our Lord Jesus Christ [God] send me your Spirit; instill the wisdom of your Holy Spirit into my heart; protect my soul and body, every limb in my body, every fiber of my being, from all possible harm and all traps the Devil may set for me and every temptation to sin. Teach me to give you thanks, O Father, Son, and Holy Spirit.
