Is the Christian Old Testament the same as the Jewish Bible?

What Is the Tanakh?

The Holy Bible we have today is basically two parts - the Old Testament and the New Testament. The earliest form of the Old Testament was something that took shape in Jewish communities over several centuries. It was called the Mikra. You may know it better by its later name - the Tanakh.

The Tanakh is an acronym. Three Hebre
w letters, each standing for one section: the Torah, the Nevi'im, and the Ketuvim - or in English, the Law, the Prophets, and the Writings.

T - N - K
T TorahThe Law
N Nevi'imThe Prophets
K KetuvimThe Writings

The first section is the Torah - five scrolls, the foundation, the law given through Moses. You might also know these five books by their Greek name, the Pentateuch. This section was so central that it is still read in its entirety in Jewish synagogues every single year.

Torah (Law) - 5 scrolls
1 Genesis
2 Exodus
3 Leviticus
4 Numbers
5 Deuteronomy

The second section is the Nevi'im - the Prophets. This contains both the Former Prophets and the Latter Prophets. Among the Latter Prophets are what we call the twelve minor prophets. But in the Tanakh, these twelve were compiled together onto a single scroll and simply called The Twelve.

Nevi'im (Prophets) - 8 scrolls
Former Prophets
1 Joshua
2 Judges
3 Samuel
4 Kings
Latter Prophets
5 Isaiah
6 Jeremiah
7 Ezekiel
8 The Twelve - Hosea, Joel, Amos, Obadiah, Jonah, Micah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah, Malachi - one scroll

The third and final section is the Ketuvim - the Writings. Psalms, wisdom literature, and some history. This was the last section to be formally recognized as Scripture.

Ketuvim (Writings) - 11 scrolls
Poetry
1 Psalms
2 Proverbs
3 Job
Five Scrolls (Megillot)
4 Song of Songs
5 Ruth
6 Lamentations
7 Ecclesiastes
8 Esther
History and Prophecy
9 Daniel
10 Ezra-Nehemiah
11 Chronicles

Together, these three sections make up the Tanakh - 24 scrolls, 24 books.

What Happened with the Septuagint

Here is where it gets interesting. Starting around 250 BC, Jewish scholars in Alexandria began translating the Hebrew Scriptures into Greek. This translation took over a century to complete, and we call it the Septuagint.

Hebrew is an extraordinarily compact script. As we have covered in an earlier episode, it was written in scriptio continua - continuous script, no spaces, no vowels. Greek, on the other hand, had vowels and took up significantly more physical space on a scroll. So some books that fit on a single Hebrew scroll could no longer fit on a single Greek scroll.

Tanakh - one scrollChristian OT - split into
Samuel1 Samuel, 2 Samuel
Kings1 Kings, 2 Kings
Chronicles1 Chronicles, 2 Chronicles
Ezra-NehemiahEzra, Nehemiah
The TwelveHosea, Joel, Amos, Obadiah, Jonah, Micah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah, Malachi

The books were also regrouped. The Tanakh's three-part structure - organized by authority - became a four-part structure organized by genre: Law, History, Poetry, and Prophecy.

BookIn the TanakhMoved to in Christian OT
RuthKetuvim (Writings)OT History, after Judges
LamentationsKetuvim (Writings)Major Prophets, after Jeremiah
DanielKetuvim (Writings)Major Prophets, after Ezekiel
Song of SongsKetuvim (Writings)Wisdom and Poetry

That restructuring carried through Latin, then into English. And that is the shape of the Christian Old Testament we have today. The Tanakh has 24 books. The Christian Old Testament has 39 - not because books were added or removed, but entirely because of splitting and recounting.

Same Words, Different Ending

The reordering also changes how each collection ends - and that matters more than you might think.

// Tanakh ends with 2 Chronicles
Cyrus telling the exiles to go home and rebuild. It ends with return.
// Christian OT ends with Malachi
A prophet pointing forward, waiting for the Messiah. It ends with anticipation.

Same words. Different shape. Very different feeling at the close.

One More Thing

In Luke 24:44, when Jesus refers to the Scriptures, he says - "the Law of Moses, the Prophets, and the Psalms." Most scholars understand the Psalms here as shorthand for the entire Writings section, the first and most prominent book of the Ketuvim. Torah. Nevi'im. Ketuvim. He was describing the Tanakh.

Something to think about. Thank you for watching, and I will see you in the next one.

    This is a well articulated synopsis, especially the “interactive version”, which ought to help eliminate the debate of “other books” having been omitted from the English OT.

The Translation Spectrum - Bible Versions Explained

-
Image
KJV, NKJV, NIV, ESC, ASB, CSB - There are hundreds of English Bible translations. This is a great blessing, because people from different background and with different levels of understanding will always have a version that resonates with them, that talks to them. But it also is a problem, in the sense that it poses the question "Which one is the best?". Every translation is unique - be it the time it was written or the reason it was made. But all of them will generally lie in a spectrum. On one end of the spectrum we have the Word-for-word philosophy, where words or text are converted from one language to another. So it ends up being a literal equivalent of the original. On the other end is the Thought-for-thought philosophy, where the meaning of a text or passage is expressed using other words. Cultural references and idioms might be smoothed over, and it is worded such that a modern reader can easily understand. This side of the spectrum might be suitable for someone who ...

Ep 9: Why does The Bible have a 400-Year Gap?

-
Image
The Holy Bible is a book that was written over a span of 1500 years, lasting from around 1400 to 1500 BC, to approximately 90 AD. The last book of the Old Testament, Malachi, was written around 400 BC. Then nothing. For 400 years, God was silent. No new prophetic voices. No new scripture recognized as God-breathed. But the world around the Bible didn't stay silent. When Malachi closes, the Israelites are in their Persian rule . The Persians had actually been relatively kind to the Jews - allowing them to return from exile, rebuild the temple, and practice their religion. But Persia wouldn't rule forever. A young military genius named Alexander the Great was about to change everything. Alexander the Great conquers everything. With Alexander comes Greek culture, and that starts spreading among the Jews. Hellenization happens which is a major change for them. When Alexander died in 323 BC, his empire was divided among his generals. Judea ended up under the control of the Seleuci...

The Resurrection of Jesus Christ: Four Theories That Try to Explain It Away

-
Image
The resurrection of Jesus Christ is the heartbeat of Christianity. It is the central claim upon which the entire faith stands or falls. And because of that, it has attracted no shortage of skeptical theories over the centuries — each one ambitiously trying to offer an alternative explanation for what happened on that Sunday morning outside Jerusalem. Here we examine four of the most popular theories, and why each one ultimately fails. Theory #1: The Swoon Theory — Did Jesus Just Faint? The word swoon means to faint. This theory proposes that Jesus never actually died on the cross. Instead, he merely lost consciousness and somehow survived the beatings and the crucifixion. He then recovered, and later appeared to his disciples, who mistakenly believed they were witnessing a risen Lord. On the surface, it might sound like a plausible alternative. But when you press on the details, the theory collapses under its own weight. The Roman soldiers had every reason to make sure Jesus was...
