Before the Beginning of Any Work O Lord, bless. Or

O Lord Jesus Christ, Only-begotten Son of Thine unoriginate Father, Thou hast said with Thy most pure lips: For without Me, ye can do nothing. My Lord, O Lord, in faith having embraced Thy words, I fall down before Thy goodness; help me, a sinner, to complete through Thee Thyself this work which I am about to begin, in the name of the Father, and of the Son, and of the Holy Spirit. Amen.
