The canticle Kyrie Pantokrator or "A Song of Penitence" appears as Canticle 14 in Morning Prayer, Rite 2, of the BCP (pp. 90-91). It is compiled from several verses of the Prayer of Manasseh, included in some Greek versions of the Hebrew Scriptures. The BCP suggests it for use in Lent at Morning Prayer on Sunday, Wednesday, and Friday and at Evening Prayer on Monday. It is also a Lenten song in the Byzantine and Mozarabic rites. It is especially suitable for use in Lent and other penitential occasions.
