1) BUG: there is an addition to the text which does not appear in the text itself
2) QUESTION: is it deliberate that verse loses its line breaks in the text comparison ... it removes one element of comparison so I would prefer that it didn't
Looks like it's picking up the 'Book One' from the start of Psalms, which comes right after v24 in the Tanakh. I'll report this. Thanks.
Update: This should be correct now with the Tanakh update released last week (2010-09-30T17:17:09Z).
