Please note: Numbering of the Psalms differs — mostly by one digit, see tables — between the Hebrew (Masoretic) and Greek (Septuagint) manuscripts. Usage varies by tradition:
Uses/used Greek numbering
Uses/used Hebrew numbering
very early Protestant publications such as the 1524 Erfurt Enchiridion ;
Catholic ancient liturgical books (Roman Missals, Books of Hours , etc.);
Eastern Orthodox translations;
Peshitta tradition of the Syriac Orthodox Church (further recognizes five extra psalms — see en:Psalm 151 and en:Psalms 152–155 ).
all traditions of Judaism;
most Protestant translations (Lutheran, Anglican, Calvinist);
modern Catholic Bible editions and books of liturgy, often indicating in brackets the Septuaginta/Vulgata numbering.
In categorizing , the Hebrew numbering should be used.
Hebrew (Masoretic) numbering (preferred)
Greek (Septuagint or Vulgate) numbering
