you must have a different Bible to me.
Well, that certainly is possible.
I currently own 5 different Bibles, not including a TaNaKh, which is in Hebrew, and an interlinear Greek/English New Testament.
All of my English-language Bibles have an "Old Testament" and a "New Testament."
The "Old Testament" (again, in all of the English-language Bibles ... the Hebrew Bible has a different order which I can share with you if you're interested) is separated into 4 parts:
The first is called the "Pentateuch," and includes Genesis, Exodus, Leviticus, Numbers, and Deuteronomy.
The second part is called "The Historic Books" or sometimes "The Early Prophets," and includes Joshua, Judges, Ruth, 1 & 2 Samuel, 1 & 2 Kings, 1 & 2 Chronicles, Ezra, Nehemiah, and Esther.
The next section is called the "Writings" and includes Job, Psalms, Proverbs, Ecclesiastes, and Song of Songs (sometimes called "Song of Solomon)
The final section is called "The Prophets" or "The Later Prophets," and includes Isaiah, Jeremiah, Lamentations, Ezekiel, Daniel, Hosea, Joel, Amos, Obadiah, Jonah, Micah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah, and Malachi.
The "New Testament" is also separated into 4 parts:
First, we've got the Gospels: Matthew, Mark, Luke, and John.
Next, we have what one of my pastors liked to call, "Luke: The Sequel," The Acts of the Apostles.
After that, we have the Epistles (or "letters"): Romans, 1 & 2 Corinthians, Galatians, Ephesians, Colossians, 1 & 2 Thessalonians, 1 & 2 Timothy, Titus, Philemon, James, 1 & 2 Peter, 1 2 & 3 John, and Jude.
Last but not least, we have the Revelation of John.
If this differs from your Bible at all, please let me know how it's different, and we can discuss it more. I would be very interested to hear how your Bible is different.
