Judaism, like Christianity and Islam, traces its roots to Abraham, and therefore, these religions are also called Abrahamic religions. Abraham (birth name Abram) is the first of the three biblical patriarchs. His story is told in the Book of Genesis. According to Jewish tradition and the Bible's internal chronology, Abraham was born in the year 1948 from Creation, which is 1813 BCE. The Genesis narrative of Abraham traces his descent from Shem, the father of Semitic peoples, and describes his faith, journeys, and legacy in believing in the God of heaven and earth, and departing from his idol-worshiping father and homeland to settle in the land of Canaan which God promised to him and his seed.
