What is the difference between the Torah, the Pentateuch, and the Tanakh?

The Torah and the Pentateuch are the Hebrew and Greek names for the first five books of the Old Testament of the Holy Bible. The word “Torah” in Hebrew can be translated to a number of things, namely instruction, teaching, or even “hitting the mark.” The word “Pentateuch” in Greek means “five books.” The books represented in these definitions are Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. It should be noted that these five books contain the Law of Moses which contains the central theological precepts of Orthodox Judaism. “Tanakh” is an acronym for “Torah,” “Nevi’m,” and “Ketuvim.” The Tanakh can be described as the Old Testament in its entirety, with its books having been divided into categories. The Torah is the first five books of the Old Testament; The “Nevi’im” which is a word that means “prophets” or “spokespeople,” contains the stories of the prophets of Israel, and gives documentation of the prophets’ guidance, prophecies, and warnings for Israel. Here is a list of the Nevi’im in the Tanakh.

Joshua
Judges
I Samuel
II Samuel
I Kings
II Kings
Isaiah
Jeremiah
Ezekiel

And a list of the Twelve Prophets of the Nevi'im is as follows: Hosea Joel Amos Obadiah Jonah Micah Nahum Habakkuk Zephaniah Haggai Zechariah Malachi

The “Ketuvim,” a Hebrew word that means “writings,” is Bible narratives that generally tell stories of chivalry, romance, war, lamentation, prophecy, and palace intrigue, all within historical contexts. The Ketuvim generally contains very poetic literary devices, and like the Torah and the Nevi’im, it covers the lives, words, and actions of specific people throughout its narrative. Here is a list of the Ketuvim in the Tanakh.

Psalms
Proverbs
Job
Song of Songs
Ruth
Lamentations
Ecclesiastes
Esther
Daniel
Ezra
Nehemiah
I Chronicles
II Chronicles
