Numbering and Naming the Psalms

In the January 9th/Day 9 podcast I, rather awkwardly, noted a discrepancy which exists in the numbering of the psalms. This discrepancy can cause great confusion for the unaware. Prior to the Protestant movement, all Christians east and west numbered them in the same manner. As Protestants began to produce translations into the European vulgar tongues, they were biased in favor of the (medieval) Masoretic Hebrew text of the Old Testament. The Hebrew text numbers the Psalms in a slightly different manner. Psalm 9 in the Hebrew system is broken into Psalms 9 and 10; likewise Psalm 146 and 147, in the historically christian system, are amalgamated into Psalm 147 in the Hebrew numbering. The numbers, in comparison, are one off between psalms 9 and 147. Protestant and more recent Catholic Bibles follow the Hebrew numbering system. Catholic (and Ecumenically minded Protestant) translations usually include the other number in parenthesis. The Douay Rheims translation, which I am using for the podcast, utilizes the older traditional christian numbering.

There is also another, older, reference system used by western Christians which I would like to draw attention to. That is, referring to a given psalm by it's Latin incipit. An "incipit" is the first few words of the text. For example, in the Latin Vulgate Bible, Psalm 1 begins 'Beatus vir qui non abiit in consilio impiorum,' so it would be referred to as "the psalm Beatus Vir". The Douay Rheims translation includes these references which I appreciate. It may be of interest that the Anglican/Episcopalian Book of Common Prayer in its Psalter also utilizes this reference system (though it uses the Hebrew numbers) as can be seen in the image below.
