Asperges Me is a Latin antiphon said or sung at a Roman Catholic Solemn Mass in all seasons except the Easter (Paschal) season and Palm Sunday. It traditionally accompanies the Asperges, the ritual sprinkling of the congregation by the celebrant with holy water, as part of an entrance ritual, symbolising the cleansing of the people. Its words are taken from Psalm 51 (50): It is followed by the conventional doxology (except on the first Sunday of Passiontide): The antiphon is then recited a second time.
