At the Aposticha, these stichera idiomela, in Tone I—

He Who of old spake with Moses on Mount Sinai in images, saying: “I am He Who is”, today, transfigured before His disciples on Mount Tabor, hath shown forth the pristine beauty of His countenance, having taken upon Himself human nature. And having set before them Moses and Elijah as witnesses to this grace, He made them partakers of gladness who, for the sake of the Cross, proclaim His glorious and saving resurrection.
