Judaism (Hebrew: יַהֲדוּת, romanized: Yahăḏūṯ) is an Abrahamic, monotheistic, ethnic religion that comprises the collective spiritual, cultural, and legal traditions of the Jewish people. Religious Jews regard Judaism as their means of observing the Mosaic covenant, which they believe was established between God and the Jewish people. The religion is considered one of the earliest monotheistic religions.
Judaism as a religion and culture is founded upon a diverse body of texts, traditions, theologies, and worldviews. Among Judaism's core texts are the Torah (Biblical Hebrew: תּוֹרָה, lit. 'Teaching'), the Nevi'im (נְבִיאִים, 'Prophets'), and the Ketuvim (כְּתוּבִים, 'Writings'), which together compose the Hebrew Bible. In Modern Hebrew, the Hebrew Bible is often referred to as the Tanakh (תַּנַ׳׳ךּ, Tanaḵ)—an acronym of its constituent divisions—or the Miqra (מִקְרָא, Miqrāʾ, '[that which is] called out'). The Hebrew Bible has the same books as Protestant Christianity's Old Testament, with some differences in order and content.
