"Let us dance in spirit with David; to-day the Ark of God [the Theotokos] is at rest."
"When the Ark of God [the Theotokos], departing from Mount Sion for the heavenly country, was borne on the shoulders of the Apostles, it was placed on the way in the tomb. First it was taken through the city, as a bride dazzling with spiritual radiance, and then carried to the sacred place of Gethsemane, angels overshadowing it with their wings, going before, accompanying, and following it, together with the whole assembly of the Church. King Solomon compelled all the elders of Israel in Sion to bear the ark of the covenant of the Lord from the city of David, that is Sion, to rest in the temple of the Lord, which he had built, and the priests took the ark and the tabernacle of the testimony, and the priests and levites raised it. And the king and all the people sacrificed numberless oxen and sheep before the ark. And the priests carried in the ark of the testimony of God into its place, into the Holy of Holies, beneath the wings of the cherubim. So is it now with the dwelling-place of the true ark, no longer of the testimony, but the very substance of God the Word. The new Solomon, the Prince of peace, the Creator of all things in the heavens and on the earth, assembled together to-day the supporters of the new covenant, that is the Apostles, with all the people of the saints in Jerusalem, brought in her soul through angels to the true Holy of Holies, under the wings of the four living creatures, and set her on His throne within the Veil, where Christ Himself had preceded her. Her body the while is borne by the Apostles' hands, the King of Kings covering her with the splendour of His invisible Godhead, the whole assembly of the saints preceding her, with sacred song and sacrifice of praise until through the tomb it was placed in the delights of Eden, the heavenly tabernacles."
