In Old Russian hymns one sporadically observes the letter Э, incorporated in the text of a hymn. The author argues that this letter refl ects some Hebrew phrases referring to the name of God: he establishes connections between the hymnographic Э and some specifi c hebraisms in the Russian Old Testament manuscripts. The article deals both with the origin of the letter Э and its subsequent evolution.
The paper is dedicated to Hebrew phrases referring to God found in some Russian codices of the Pentateuch of the XV-XVII centuries. The author examines the origin of this phenomenon.
