Genesis 2:15 (KJV)

And a river went out of Eden to water the garden; and from thence it was parted, and became into four heads.

The name of the first is Pison: that is it which compasseth the whole land of Havilah, where there is gold;

And the gold of that land is good: there is bdellium and the onyx stone.

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

And the name of the third river is Hiddekel: that is it which goeth toward the east of Assyria. And the fourth river is Euphrates.

And the LORD God commanded the man, saying, Of every tree of the garden thou mayest freely eat:

But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.

And the LORD God said, It is not good that the man should be alone; I will make him an help meet for him.

And out of the ground the LORD God formed every beast of the field, and every fowl of the air; and brought them unto Adam to see what he would call them: and whatsoever Adam called every living creature, that was the name thereof.

And Adam gave names to all cattle, and to the fowl of the air, and to every beast of the field; but for Adam there was not found an help meet for him.
