When the fall of man occur in the Garden of Eden ,it seems that the river that was watering the Garden of Eden was perfection. When God removed them from the Garden of Eden, curse was the ground (dust) on earth that they where made from. This river in Genesis 2:10 was cut off from the world in order that curruption (the curse) take it toll on the earth and everything living in it. sickness death etc.
Ezekiel 47
And he said to me, “This water flows toward the eastern region and goes down into the Arabah, and enters the sea;[SUP]
b[/SUP] when the water flows into the sea, the water will become fresh.[SUP]
c[/SUP]
9And wherever the river goes,[SUP]
d[/SUP] every living creature that swarms will live, and there will be very many fish. For this water goes there, that the waters of the sea[SUP]
e[/SUP] may become fresh; so everything will live where the river goes.
