Isaac of Nineveh : The same applied to the plate placed on top of the ark, from which the priest learned from God whatever was necessary by revelation once a year, when the high priest entered, at the solemn moment of prayer, while all the tribes of Israel were gathered and standing in awe and trembling in the outer tent in prayer. The high priest entered the inner sanctuary, and while he lay prostrate on his face, the utterances of God were audible from within that plate which was over the ark, by means of an awesome and ineffable revelation. How fearful was that mystery which was carried out on that occasion. It is the same with all the revelations and visions which have come to the saints: they have all occurred at the time of prayer. — DISCOURSE 22
