According to the Hebrew Bible, Moses led the Israelites out of Egypt, and received the Torah of Judaism from God on Mount Sinai. The Torah contains the life story of Moses and his people until his death at the age of 120 years, according to some calculations in the year 2488, or 1272 BC. Consequently, "may you live to 120" has become a common blessing among Jews.
Moses's greatest legacy was probably expounding the doctrine of monotheism, which was not widely accepted at the time, codifying it in Jewish religion with the 1st Commandment, and punishing polytheists. He is revered as a prophet in Judaism, Christianity, and Islam.
