Why did the Jews originally leave the holy land to wander the earth?
The history of the Jewish people begins with Abraham, and the story of Abraham begins when G-d tells him to leave his homeland, promising Abraham and his descendants a new home in the land of Canaan. This is the land now known as Israel, named after Abraham’s grandson, whose descendants are the Jewish people. The land is often referred to as the Promised Land because of G-d’s repeated promise as written in the bible. The hews wondered in the desert for 40 years after Moses took the Jews out of slavery from Egypt and into the Sinai, where they then wondered for 40 years as G-d told them to before returning to the land of Milk and Honey, Israel.
