The present edition of the "Psalter with Brief Interpretation" by the late Pan. N. Trembelas is a faithful reprint of the one made in 1966, but in a smaller format. We hope that, on the one hand, the smaller size and, on the other hand, the simplification of the meanings of the sacred psalms through the brief interpretation, will contribute to the circulation of this divinely inspired text of the Old Testament even more among the faithful children of the Church and, with God's help, bring much spiritual edification.
