When applying canonical criticism, it is important to refer to the scripture in the appropriate context e.g. Esther vs. Greek Esther or Daniel (Hebrew) and Daniel (Greek). In my particular case, my default Bible is NRSV (or NRSVue, depending on my mood) in which the Prayer of Manasseh is an independent book. It is not the final chapter of 2 Chronicles nor is it part of Odes which is absent from my default Bible. Yet the Bible Study Builder insists on using an Odes reference. The content and chapter numbers of the Book of Odes varies - is the prayer 8, 12, 13 … The result is that the questions need to be rewritten to not be nonsensical and the version of Odes being reference is inscrutable.
P.S. to add to the insult, the questions appear to miss the fact that the text is an example of a personal lament usually studied for form and content of repentance and that the Book of Odes is a collection of independent texts held together solely by their liturgical use.
But then again Factbook and Bible Lesson Build disagree on what Ode 8 is …
From Perplexity (please Jason don't make me waste time rewriting this)
In other words:
In the full 14‑Ode list based on Alexandrinus, Prayer of Manasseh is indeed Ode 12.
When some sources speak of it as Ode 8, they are using a shorter Greek Odes set or a renumbered selection (e.g., omitting some Old Testament or New Testament canticles and counting only a subset used liturgically), so the same canticle lands on a different ordinal.
So your sources that give Ode 12 in Codex Alexandrinus are following the standard 14‑Ode enumeration of the Alexandrinus Biblical Odes, and that is the more precise way to cite it when you are explicitly working from that codex.
But Logos can't even be consistent when it chooses an unusual position:
My patience at identifying the problems in this mess ran out at this point.
