The Jewish people believe by definition that G‑d is the single creator and animator of the world. He has no helpers, no children and no rivals. Judaism mandates that Jewish people follow the mitzvot, Divine commandments. Major mitzvot include resting and celebrating on Shabbat and Jewish holidays, eating kosher foods, studying Torah, and living in accordance with its teachings. Judaism is based on the G‑d's covenant with the forefathers and the revelation at Sinai, when He chose the Jewish people as His own and they committed to follow the Torah.
