Judaism was the first monotheistic religion in human history (over three thousand years).
Despite being the smallest in number of believers (about 15 million, most of them in North America and Israel), it is one of the great Abrahamic religions, along with Christianity and Islam.
Judaism is a word of Greek origin (Judaïsmós) for the toponym "Judah".
According to Jewish tradition, God would have made a covenant with the Hebrews, making them the elect people who will enjoy the promised land.
This covenant came with Abraham and his offspring and was strengthened by the revelation of divine Laws to Moses on Mount Sinai.
