Open my mouth, O Lord, to bless Thy Holy Name: cleanse my heart from all vain, evil and distracting thoughts; enlighten my understanding, inflame my will, that I may worthily recite this Office with intention and devotion, and deserve to be heard in the presence of Thy Divine Majesty. Through Christ our Lord. Amen.

O Lord, in union with that divine intention with which Thou didst praise God on Earth, I offer to Thee these Hours.
