O God, cleanse me a sinner
Orthodox
O God, cleanse me a sinner, for I have never done anything good in Thy sight; but deliver me from the evil one, and let Thy will be done in me, that I may open mine unworthy mouth without condemnation, and praise Thy holy name: of the Father, and of the Son, and of the Holy Spirit, + now and ever, and unto the ages of ages. Amen.
