What is the hebrews main religious scripture called?

Answer 1

The main Jewish scripture is the Torah, which consists of the first five books of the Hebrew Bible--what Chrstians call the Old Testament. Jews don't call it the Old Testament because to them there has been no New Testament (covenant with God); they feel theirs is still valid. The Torah is believed to be the word of God, transmitted by Moses. The Hebrew term for the Old Testament is Tanakh.
Torah
The main Hebrew scriptures were collectively called "The Bible" or "The Tanakh".
It's called the Bible or the Tanakh (תנ״ך)

Answer 2

The Jewish holy book is the Tanakh (Jewish Bible), containing the Torah and the prophetic books.
Tanakh is a Hebrew acronym of T, N, K which stands for the three parts of the Tanakh: Torah, Nevi'im (Prophets), and Ketuvim (Writings).
A) The Torah, also called the Pentateuch, is the primary Jewish holy book. It is comprised of the five Books of Moses (also called the Books of the Law). The Torah was given by God to Moses (Exodus 24:12), who transmitted it to the people and wrote it (Deuteronomy 31:24). Its chief purpose is to teach the laws of Judaism; and it also teaches us historical highlights, attitudes, guidance, beliefs and more.
1-5: The Torah (the Five Books of Moses):
1) Bereisheet (Genesis)
2) Shemot (Exodus)
3) Vayikra (Leviticus)
4) Bamidbar (Numbers)
5) Devarim (Deuteronomy)
B) Nevi'im, The Prophets. The Jews see the book of Prophets as the Divinely-inspired story of their past and the relationship between God and Israel.
The prophets were called upon by God to guide the people and to guide the king. While the king had authority in national matters of state, and the Sanhedrin (Sages) had say in Torah-rulings and halakha (law), the prophets spoke in matters of ethics, of belief, of loyalty to God, and behavior. They rebuked the people at God's command, they predicted events which God revealed to them, they taught through Divine inspiration, and they provided optimism and hope with the prophecies of eventual Redemption.
Jewish tradition (Talmud, Bava Batra 14b) states that the prophetic books were written by the authors whose names they bear: Joshua, Samuel, Isaiah, Jeremiah, Ezekiel, Hosea, Joel, Amos, etc. Judges is credited to Samuel, Kings was written by Jeremiah. The Prophets contain a total of 8 books according to the Jewish count.
6-9: The Nevi'im Rishonim (the Early Prophets):
6) Yehoshua (Joshua)
7) Shoftim (Judges)
8) Shemuel (Samuel I and II)
9) Melachim (Kings I and II)
10-13: The Nevi'im Acharonim (the Later Prophets):
10) Yeshayahu (Isaiah)
11) Yirmiyahu (Jeremiah)
12) Yechezkel (Ezekiel)
13) Trei Asar ("The Twelve Prophets" or Minor Prophets)
Books and Prophets within Trei Asar:
Hoshea (Hosea)
Yoel (Joel)
Amos
Ovadiah (Obadiah)
Yonah (Jonah)
Michah (Micah)
Nahum
Havakkuk (Habakkuk)
Zephaniah
Haggai
Zechariah
Malachi
C) Ketuvim, Writings. The Ketuvim contains the remaining History Books: Daniel, Lamentations, and others.
Some of these prophetical chapters (or books) detail Israelite history and past events, some predict events, some serve to comfort the nation, some speak of prayer and love of God, and some speak of life, experience and wisdom.
Jewish tradition (Talmud, Bava Batra 14b) states that the prophetic books were written by the authors whose names they bear: Daniel, Ezra, Nehemiah, etc. Ruth was written by Samuel; Lamentations was written by Jeremiah; Psalms was set in writing by King David; Chronicles was written by Ezra; Proverbs, Song of Songs and Kohellet (Ecclesiastes) were written by King Solomon; and Esther was written by Mordecai and Esther. Concerning Job, the Talmud states more than one opinion as to when it was written. The Writings consists of 11 books by the Jewish count:
14-16: The "Sifrei Emet"
14) Tehillim (Psalms)
15) Mishlei (Proverbs)
16) Iyov (Job)
17-21: The "Five Megilot" (Five Scrolls)
17) Shir Hashirim (Song of Songs)
18) Ruth
19) Eichah (Lamentations)
20) Kohelet (Ecclesiastes)
21) Esther
22-24: The rest of the Writings:
22) Daniel
23) Ezra-Nehemiah
24) Divrei Hayamim (Chronicles I and II)
Further information:
The term "Torah" can refer loosely to the entire Jewish Bible.
Tradition places the sealing of the Tanakh's canon around 340 BCE.
