Man's Mandate and the Prohibition

Genesis 2:15-17

And the LORD God took the man, and put him into the garden of Eden to dress it and to keep it.

¶ And the LORD God commanded the man, saying, Of every tree of the garden thou mayest freely eat:

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.
