Genesis 2:8-9, 17

Then YAHWEH-God planted a lush garden paradise in the East, in the Land of Delight, and there he placed the man he had formed. YAHWEH-God made all kinds of beautiful trees to grow there—fruitful trees to satisfy the taste. In the middle of the garden, he planted the Tree of Life and the Tree of the Knowledge of Good and Evil.

But you must not eat of the Tree that gives the knowledge of good and evil, for when you eat from it you will most certainly die.”
