Final answer:
In Jewish tradition, circumcision is a practice that originated from Abraham's covenant with God, but other central beliefs include Sabbath observance, monotheism, and ritual sacrifices.
Step-by-step explanation:
According to Jewish tradition, the belief that has significantly stemmed from Abraham's covenant with God includes circumcision, as a mark of this promise. However, other beliefs and practices such as Sabbath observance, monotheism, and ritual sacrifices also play central roles in Jewish religious life. Sabbath observance, for example, is marked by rest on the seventh day of the week, honoring one of the Ten Commandments. Monotheism, the worship of one God, became a distinctive feature of the Jews' religious identity after the Exodus and is a critical element of Judaism, Christianity, and Islam. The practice of ritual sacrifices was an important aspect of the Jewish faith, especially before the Second Temple's destruction in 70 CE.
