The Land of Israel (Hebrew: אֶרֶץ יִשְׂרָאֵל‎, Eretz Yisrael) is, according to the Hebrew Bible, the region which was promised by God to the descendants of Abraham through his son Isaac and to the Israelites, descendants of Jacob, Abraham's grandson. This land forms part of the Abrahamic, Jacob and Israel covenants. Mainstream Jewish tradition regards the promise as applying to all Jews. The Biblical definitions of Eretz Yisrael encompass different regions; the actual area defined by these Bible passages is also subject to differences of opinion.
