Man's Instruction In The Garden of Eden

Genesis 2:15-17

15  And the LORD God took the man, and put him into the garden of Eden to dress it and to keep it. 
16  And the LORD God commanded the man, saying, Of every tree of the garden thou mayest freely eat: 
17  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.
