The word AGPEYA takes origin from the Coptic word TI-AGP, which literally means the hour.
The Book of "AGPEYA":
The book of AGPEYA contains the seven canonical prayers which have been cherished and practiced by the faithful Copts of the Orthodox Church of Alexandria, Egypt.
The Psalms as the core of the Seven Prayers:
The seven canonical prayers have their root in the Psalms. David said; "Seven times a day, do I praise you of your righteous Judgement" (Psalm 118:164). The numerical order of Psalms in this book of prayer conforms to the Coptic Translation.
The prayer of Veil is said daily in the monasteries, after the prayer of the Twelfth Hour and before the Prayer of Midnight. The present position of this Prayer after the Prayer of Midnight aims to facilitate the daily usage by laymen.
