Genesis 2:8-9

And the LORD God planted a garden (oasis) in the east, in Eden (delight, land of happiness); and He put the man whom He had formed (created) there. And [in that garden] the LORD God caused to grow from the ground every tree that is desirable and pleasing to the sight and good (suitable, pleasant) for food; the tree of life was also in the midst of the garden, and the tree of the [experiential] knowledge (recognition) of [the difference between] good and evil. [Rev 2:7; 22:14, 19]
