GENESIS 2:13

[NKJV]

The name of the second river is Gihon; it is the one which goes around the whole land of Cush.
 

[AKJV]

And the name of the second river is Gihon: the same is it that compasses the whole land of Ethiopia.

According to the Bible verse above, "The Second River (Gihon) and the River around the whole land of Ethiopia, is basically the same." From the time and place this Second River (Gihon) left from the River of Eden, till it surrounded the land of Ethiopia (Cush), it remained the same River called Gihon. Whether other rivers broke out of it or other rivers joined it along the way, the point is that it remained "The Same River" from the second branch off the River of Eden to the compassing of the Land of Ancient Ethiopia.

This was not just about remaining the same river through the distance between the land of Ethiopia and the land of Eden, but also about remaining the same river through thousands of years from when Adam was in Eden to when and after the grandson of Noah, called "Cush" or "Ethiopia" was born and allocated that land, even to the point when this part of the Book of Genesis was written. That River was the same; not changed.

Mankind did not remain the same from Adam in the Garden to Ethiopia, the father of the Black Race or Africans after the flood. So Mankind changed from Eden to Ethiopia land, but Gihon the second river was the same from Eden to Ethiopia land. There are people you cannot say are the same from where/when they began to where they are now, because they changed though still bearing the same names: some have grown worse than they were before, and other grown better than they were before.

But here was a River named Gihon, which passed through many lands and flood between when it became the second branch off the River of Eden to when it's surrounded the land of Cush, and neither its name or Identity was changed for it to forget where it was coming from by reason of where it had been. If anything, it rather grew in size and potentials on arriving the land of Cush, and not declined in potency.

The name "Gihon" means "Stream" in Hebrew language. The second river is named Gihon or named "Stream." May our Streams, Streamings and Fountains, retain their integrity and identity no matter the large distances, places or times covered.
