O Lord, open my lips; and my mouth shall show forth your praise.
Read Chapter 51
Augustine of Hippo
20. "O Lord, my lips Thou shall open, and my mouth shall tell of Thy praise" (ver. 15). "Thy praise," because I have been created: "Thy praise," because sinning I have not been forsaken: "Thy praise," because I have been admonished to confess: "Thy praise," because in order that I might be secured I have been cleansed.
