Jacob (later given the name Israel) is regarded as a Patriarch of the Israelites. According to the Book of Genesis, Jacob (; Standard ) 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. Jacob had twelve sons and at least one daughter, by his two wives, Leah and Rachel, and by their handmaidens Bilhah and Zilpah.
