Judaism is one of the oldest monotheistic religions originating around 1800 BC. It began with Abraham and his descendants who God promised to protect if they obeyed him. The core beliefs of Judaism are that there is one God, Yahweh, and that individuals can have personal relationships with him. The most important Jewish text is the Torah, which was given to Moses by God and contains Jewish laws and history. Jews worship at synagogues, where the Torah is kept inside the Ark.
