As the bishop is greeted at the door and clothed in the mantle by the subdeacons, the choir sings:
From the rising to the setting of the sun, the name of the Lord is to be praised. Blessed be the name of the Lord from this time forth and for evermore.
The bishop blesses the censers, venerates the Cross which is brought to him by the vested priest, then proffers it for veneration by the higher clergy. He is then escorted to the solea where the deacon says the preparation prayers on his behalf, during which the choir sings the zadostoinik, which is usually It is truly meet to bless thee...
but if a festal or seasonal zadostoinik is appointed to be sung at the Anaphora instead of It is truly meet...
, it is sung at this point as well. When this has finished, the bishop turns to the people, and blesses them, while the choir sings the Ton Dhespotin
The bishop is escorted back to the bema in the middle of the nave (or enters the altar if he chooses to vest simply), where he is relieved of the mantle and vested by the subdeacons. During the vesting, the choir sings:
Thy soul shall rejoice in the Lord, for he hath clothed thee with the garment of salvation, and with the robe of gladness hath he encompassed thee. As a bridegroom he hath set a crown upon thee, and as a bride hath he adorned thee with ornament.
(This is also the first of the vesting prayers which are read by the deacon while the bishop is being vested.)
Also, in some places/at certain times:
The prophets proclaimed thee from on high, O Virgin: the Jar, the Staff, the Tablets of the Law, the Ark, the Candlestick, the Table, the Mount Uncloven (Daniel 2:49), the Golden Censer and the Tabernacle, the Gate Impassable (Ezekiel 44:1-3), the Palace (1 Chronicles 29:1) and Ladder, and the Throne of Kings.
When the bishop is fully vested, the subdeacons collect the trikiri and dikiri from the deacons (who, throughout the vesting, have been holding them on the solea while censing the bishop), and present them to the bishop. He blesses the people while the choir again sings the Ton Dhespotin
. Then the reader begins the Hours as usual.
I hope this helps.
