Let All Mortal Flesh Keep Silence

"Let All Mortal Flesh Keep Silence" is an ancient chant of Eucharistic devotion based on the verses taken from Habakkuk taken from one of the books of the 12 minor prophets of Bible. The original was composed in Greek as a Cherubic Hymn for the Offertory of the Divine Liturgy of St James in the fourth Century AD, with local Churches adopting arrangements in Syriac. In modern times, the Ralph Vaughan Williams arrangement of a translation from the Greek by Gerard Moultrie to the tune of Picardy, a French medieval folk melody, popularized the hymn among Christian congregations that worship liturgically.
