God, the glory, planted a garden in Eden in the east, and he put there the man whom he had formed. And God, the glory, caused to grow out of the ground all kinds of trees, desirable to look upon and good for food, and the Tree of life in the middle of the gardenand the tree of the knowledge of good and evil.
And commanded the man, saying, Of every tree of the garden thou mayest eat: but of the tree of the knowledge of good and evil, of it thou shalt not eat: for in the day that thou eatest thereof thou shalt surely die.
This tree also stood in the middle of the garden, as is unmistakably clear from the next quotation (Eve answered the serpent):
Of the fruits of the tree [of knowledge] which is in the midst of the gardens God has said: You shall not eat of it, and you shall not touch it, lest you die!
