The holy book of Judaism is the Tanakh, also known as the Hebrew Bible. It consists of three main sections: the Torah, the Prophets, and the Writings. The Torah (also referred to as the Pentateuch) contains the first five books of the Bible - Genesis, Exodus, Leviticus, Numbers, and Deuteronomy, and is considered the most sacred part of the Tanakh. The Prophets include books such as Isaiah, Jeremiah, and Ezekiel, while the Writings include Psalms, Proverbs, and the Book of Job, among others. The Tanakh contains the central teachings and beliefs of Judaism, and is considered the foundation of Jewish law and customs.
