It's a covenant. It's a deal that if you listen to me, if you follow my rules, if you pray to me and worship me and honor me, then I'm going to give you really great land and your descendants are going to rule over that great land. That's the deal. You do what I say. I give you this land, which is going to be Canaan, which eventually we're going to call Israel, which people also refer to as ancient Palestine. And that is at the root of Judaism. It's a covenant.
