He translated seven psalms, a collection known as the "Penitential Psalms". Psalm 51 is one of the penitential psalms. All psalms and canticles are accompanied by antiphons. Bible teachings are evident in some published Doukhobor psalms, hymns, and beliefs. These prayers are verses taken directly from the Old Testament, usually the Psalms. The antiphons before the psalms were only intoned. Three of them (Psalms 131, 133, and 134) have only three verses. Additionally many Biblical Psalms, styled as songs, were written specifically about Jerusalem. Anglican chant is a method of singing prose versions of the Psalms. Communion was celebrated monthly and congregational singing of the psalms was encouraged. The Bible mentions the Ziz in Psalms 50&colon;11. The first two psalms, 113 and 114, were recited before the meal. Instead, a Tract is chanted, usually with texts from the Psalms. Hallel (communal recitation of Psalms -) follows. The two also worked at a metrical edition of the Psalms.
