Deliver us, Lord, from every evil, and grant us peace in our day. In your mercy keep us free from sin and protect us from all anxiety as we wait in joyful hope for the coming of our Savior, Jesus Christ our Lord. Amen.

This prayer is called the “embolism,” a word for a short prayer inserted into another prayer. According to the 1913 Catholic Encyclopedia, “[t]he embolism may date back to the first centuries, since, under various forms, it is found in all the Occidental and in a great many Oriental, particularly Syrian, Liturgies.”
Original in Latin:
Libera nos, quæsumus, Domine, ab omnibus malis, da propitius pacem in diebus nostris, ut, ope misericordiæ tuæ adiuti, et a peccato simus semper liberi, et ab omni perturbatione securi: expectantes beatam spem et adventum Salvatoris nostri Iesu Christi.
This short prayer is often inserted into the Lord’s Prayer in this manner:
Our Father, who art in heaven, hallowed be thy name, thy kingdom come, thy will be done on earth as it is in heaven. Give us this day our daily bread; and forgive us our trespasses, as we forgive those who trespass against us; and lead us not into temptation, but deliver us from evil.
Deliver us, Lord, from every evil, and grant us peace in our day. In your mercy keep us free from sin and protect us from all anxiety as we wait in joyful hope for the coming of our Savior, Jesus Christ our Lord.
For thine is the kingdom and the power and the glory forever and ever. Amen.
