Divine Liturgy
Borrowed from the old Divine Liturgy of St. James, the ancient hymn "Let all mortal flesh keep silent" replaces the Cherubikon in the Divine Liturgy of St. Basil the Great in the Eucharist celebrated in the morning of Holy Saturday. The Byzantine Rite only makes use of the Divine Liturgy of St. Basil ten times a year, and during most of the liturgical year the Divine Liturgy of St. John Chrysostom is used instead. However, even in the dates when the Divine Liturgy of St. Basil is used, the normal Cherubikon is usually sung. It is however replaced by the anthem "Let all mortal flesh keep silent" specifically on Holy Saturday.
