Deus in adjutorium - the beginning of an hour

Day 6 / 100 day Gregorian chant challenge
I'm already running short of time to prepare these short clips, so I'm taking this from a project to make another course to follow on from my Sing the Little Office of the Blessed Virgin Mary course. This one will be on Roman Compline.
The translation is :
O God, come to my assistance. O Lord, make haste to help me. Glory be to the Father and to the Son and to the Holy Ghost. As it was in the beginning, is now, and ever shall be, world without end. Amen. Alleluia / Praise to Thee Lord Jesus Christ, King of endless Glory.
