What is omitted from the current Western, Catholic Psalter? I know that there are at least two Pslams omitted from the current Breviary, and I know that some pieces of others are missing (Psalm 136, for example, is missing the verse about dashing baby's skulls against rocks). I can't seem to find a reference to which Psalms and which verses are omitted.
The following is a list of omitted verses and Chapters from the four week plaster, currently in use. It follows modern numbering. Not Septuagint numbering.
