O Lord, open my lips; and my mouth shall show forth your praise.
All Commentaries on Psalms 51:15 Go To Psalms 51
Augustine of Hippo
AD 430
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.
