b.PSA.9 and following

[chiarcos]

There is a systematic discrepancy in psalm numbering in different families of the Bible. In our data, we normally didn't verify which numbering system applies.

• masoretic numbering (= Lutheran): in Hebrew, psalms 9 and 10 form a logical unit (one verse for every letter in the alphabet) that spans over two separate psalms
• Septuagint/Vulgate numbering (= pre-Reformation): in the Septuagint, psalms 9 and 10 were merged into psalm 9, so that all following psalms have an offset of 1 compared to Hebrew and Lutheran bibles

I would expect that medieval, orthodox and Catholic Bibles use the Septuagint numbering and that 19th c. and earlier translations are a mixed bunch. Most 20th c. Bible translations are, however, Evangelical and should use the masoretic numering.
