As I’ve noted, we have three different selections of the books of the Bible, and even their order of appearance can differ. Here they are for comparison:

HEBREW BIBLE, 24 books
- Genesis
- Exodus
- Leviticus
- Numbers
- Deuteronomy
- Joshua
- Judges
- Samuel
- Kings
- Isaiah
- Jeremiah
- Ezekiel
- The Twelve (Hosea, Joel, Amos, Obediah, Jonah, Micah, Nahum, Habakkuk, Zepaniah, Haggai, Zachariah, Malachi)
- Psalms
- Proverbs
- Job
- Song of Songs
- Ruth
- Lamentations
- Ecclesiastes
- Esther
- Daniel
- Ezra / Nehemiah
- Chronicles
- No Maccabees! And, of course, no New Testament.

VULGATE/ROMAN CATHOLIC, 46 books in Old Testament.
Also, with slight variation, used by EASTERN ORTHODOX.

And, for further complications, the books of the Apocrypha are sometimes placed between the Old Testament and the New Testaments. The order above is the one I followed in my straight-through reading.
