Eden is the place where the Garden of Eden was located, "And the Lord God planted a garden toward the east, in Eden; and there He placed the man whom He had formed," (Gen. 2:8). It is in this garden that Adam and Eve were created.
There were four rivers in the land of Eden (Gen. 2:10). They were the Pishon (Gen. 2:11), Gihon (Gen 2:13), Tigris and Euphrates (Gen. 2:14). The Garden of Eden is called the Garden of God in Ezek. 28:13.
The Garden was meant for Adam and Eve to till and keep, but they fell and were expelled from the Garden.
