Jacob (later given the name Israel) is considered a patriarch of the Israelites. According to the Book of Genesis, Jacob (/ˈdʒeɪkəb/; Hebrew: יַעֲקֹב Standard Yaʿakov) was the third Hebrew progenitor with whom God made a covenant. He is the son of Isaac and Rebecca, the grandson of Abraham, Sarah and of Bethuel, and the younger twin brother of Esau.
