The great Moses foreshadowed this day mystically by his saying, “And God blessed the seventh day”; for this is the day of quiet and rest, on which the only Son of God rested from all his Works, keeping Sabbath in the body, by means of the mystery of the dispensation taking effect in death, returning through Resurrection to what he had been, and granting us eternal life; for he alone is good and the Lover of mankind.
A hymn from the Holy Saturday Vesperal Liturgy (Divine Liturgy of St. Basil the Great) this morning. Not sure of the hymnographer (but likely Byzantine).
