Abraham is the first of the Hebrew patriarchs and a figure revered by the three great monotheistic religions—Judaism, Christianity, and Islam. According to the Bible, Abraham left the idol worshipping region of Mesopotamia, to establish a new nation in an undesignated land that he later learned was Canaan. He is identified as the father of faith through unquestionably obeying even the most difficult commands of God, including offering up his own son. Abraham received repeated promises and a covenant that his "seed" would inherit the land.
