O God, the author of peace and lover of concord, to know you is eternal life and to serve you is perfect freedom: Defend us, your humble servants, in all assaults of our enemies; that we, surely trusting in your defense, may not fear the power of any adversaries; through the might of Jesus Christ our Lord.
The Gelasian Sacramentary

1 Shout for joy to the LORD, all the earth.
2 Worship the LORD with gladness;
come before him with joyful songs.
3 Know that the LORD is God.
It is he who made us, and we are his [a] ;
we are his people, the sheep of his pasture.
4 Enter his gates with thanksgiving
and his courts with praise;
give thanks to him and praise his name.
5 For the LORD is good and his love endures forever;
his faithfulness continues through all generations.
Psalm 10o New International Version
