Glory be to the Holy, Consubstantial, life-giving and undivided Trinity: always, now and for ever: world without end.
O come, let us worship... 
And the Introductory Psalm:
Bless the Lord, O my soul. Up to the verse When Thou hast given it them, they will gather it.
And then the Choir shall sing the verses of. WHEN THOU OPENEST THINE HAND [ΑΝΟΙΞΑΝΤΑΡΙΑ]
When Thou openest Τhine hand...
Thou takest away their breath...
Thou sendest forth Τhy spirit...
The glory of the Lord...
He looketh on the earth...
I will sing unto the Lord...
My meditation of Ηim shall be sweet...
Let the sinners be consumed...
Bless Τhou the Lord, O my soul ...
O Lord, how manifold are Τhy works...
Now and for ever...
Alleluia. Alleluia. Alleluia....
And the rest of Great Vespers as usual with the order for the Breaking of Bread [see Breaking of Bread]
After the blessing of the five loaves the Reader shall recite the following verses from Psalm 33 
I will bless the Lord at all times: his praise shall continually be in my mouth. My soul shall make her boast in the Lord: the humble shall hear thereof, and be glad. O magnify the Lord with me, and let us exalt his name together. I sought the Lord, and he heard me, and delivered me from all my fears. They looked unto him, and were lightened: and their faces were not ashamed. This poor man cried, and the Lord heard him, and saved him out of all his troubles. The angel of the Lord encampeth round about them that fear him, and delivereth them. O taste and see that the Lord is good: blessed is the man that trusteth in him. O fear the Lord, ye his saints: for there is no want to them that fear him.
The rich have become poor and hungry, but they that seek the Lord shall not want any good thing.
The Choir shall repeat the verse twice.
The Priest shall not give the dismissal, but after he says
The blessing of the Lord and His mercy be upon you…
The Choir shall say: Amen.
And if there is a reading for the Feast or the saint from the Lives of the saints, the Reader shall say:
Master, give the blessing.
PRIEST: Blessed is our God....
READER: Amen. And the reading.
And after the reading the Reader shall straightway recite the Six Psalms of Mattins.
