Man's Mandate and the Prohibition

Genesis 2:15-17

And Jehovah God taketh the man, and causeth him to rest in the garden of Eden, to serve it, and to keep it.

And Jehovah God layeth a charge on the man, saying, `Of every tree of the garden eating thou dost eat;

and of the tree of knowledge of good and evil, thou dost not eat of it, for in the day of thine eating of it--dying thou dost die.'
