Psalms (some churches also sing the small number of hymns found elsewhere in the Bible) in worship, and do not accept the use of any non-Biblical hymns; examples are the Reformed Presbyterian Church of North America, the Presbyterian Reformed Church (North America) and the Free Church of Scotland (Continuing). Psalm 22 is of particular importance during the season of Lent as a Psalm of continued faith during severe testing. Psalm 23, The is My Shepherd, offers an immediately appealing message of comfort and is widely chosen for church funeral services, either as a reading or in one of several popular hymn settings; Psalm 51, Have mercy on me O God, called the Miserere from the first word in its Latin version, in both Divine Liturgy and Hours, in the sacrament of repentance or confession, and in other settings; Psalm 82 is found in the Book of Common Prayer as a funeral recitation.
