Freely

2:16 And the LORD God commanded the man, saying, Of every tree of the garden thou mayest freely eat: 

Ah, those verses that end in colons.

This is similar to, but contrasts a bit with the first chapter.  As always, we have the 'Lord' thing.  But this is parallel to 1:29, "I have given you every herb ... and every tree ... it shall be for meat".  In this case, it's the trees in the garden; in the previous case, all the plants on earth.

This part doesn't sound much like a command, but that hints at what follows the colon.
