The Christian Holy Book is The Bible.
The primary difference between the Christian Bible and the Jewish Bible is the addition of the New Testament, which fundamentally alters the relationship between God and his Creation. Additionally, the Old Testament is a rearranged version of the Jewish Bible and resorts to translations of texts and material additions not present in the Jewish Bible.

Hebrew is considered a sacred language in many religious traditions, including Judaism, where it is believed to be the language in which God communicated with humanity.
The most sacred part is the Torah, which is the first 5 books of the Hebrew Bible.
The Epistle to the Hebrews is not the same as the Hebrew scriptures. The Hebrew scriptures, known to Christians as the Old Testament, are the holy books of Judaism, also accepted as sacred by the Christian Churches. The Epistle to the Hebrews, strictly speaking not a letter, but rather an encyclical or even a sermon, is a purely Christian book thought to have been addressed to a group of Christian Jews.
All 24 books of the Hebrew Bible are considered sacred to Judaism. The primary sacred books are the books of the Torah. Secondary would be the books of the Prophets, and lastly, the Holy Writings, such as the Psalms and Proverbs.

The Tetragrammaton is a term used to refer to the four Hebrew letters YHWH (יהוה), which represent the name of God in the Hebrew Bible. It is considered sacred in Judaism and is often not pronounced aloud, with substitutes like "Adonai" or "HaShem" being used instead. In Christian contexts, it is sometimes rendered as "Jehovah" or "Yahweh." The Tetragrammaton emphasizes the concept of God's eternal and unchanging nature.
