O Thou to Whom the holy Powers sing with unending hymns and unceasing doxologies, fill our mouths with Thy praise, that we may magnify Thy holy name. And grant unto us part and inheritance with all those that fear Thee in truth and keep Thy commandments, through the intercessions of the holy Theotokos and of all thy Saints.

For to Thee belong all glory, honor, and worship, to the Father, and to the Son, and to the Holy Spirit, now and ever, and unto ages of ages. Amen.
(Fourth Prayer from the Presanctified Liturgy)
