Garden of Eden Rivers

 Genesis 2

¹⁰And a river went out of Eden (pleasure) to water the garden; and from thence it was parted, and became into four heads. ¹¹The name of the first is Pison (increase): that is it which compasseth the whole land of Havilah (circle), where there is gold; ¹²And the gold of that land is good: there is bdellium and the onyx stone. ¹³And the name of the second river is Gihon (bursting forth): the same is it that compasseth the whole land of Ethiopia (Kuwsh { koosh} Cush = "black"). ¹⁴And the name of the third river is Hiddekel (rapid): that is it which goeth toward the east of Assyria (a step). And the fourth river is Euphrates (fruitfulness).

These are thoughts only and not conclusions:

This is assuming that the Garden of Eden was where Jerusalem currently is now.

The River Increase in the land of Circle…. gold of that land is good: there is bdellium and the onyx stone  WEST (because the other three compass points are taken)

The River Bursting forth in the land of  Black   SOUTH (because Ethiopia is south)

The River Rapid toward the east of  a step    EAST

The River Fruitfulness  NORTH  (Euphrates is both north and east of Jerusalem, and East is already taken, therefore, it must be North)
