What trees could Adam eat from in the Garden of Eden?
The man was permitted to freely eat from every tree of the Garden of Eden. The sole exception was the tree of the knowledge of good and evil, which God commanded him not to eat, warning that in the day he ate of it he would surely die.
Les teaches from this passage that God placed the man in Eden to dress and keep it, and that there were no weeds, thorns, or thistles, making it a relatively mild occupation. God commanded that of every tree of the garden the man could freely eat; everything there was for him to enjoy, whether tree, vine, herb, or anything that grew. The only prohibition was the tree of the knowledge of good and evil. Eating from it would bring certain death. Les also notes the common question of why God would place such a tree before a perfect man and calls it a good question.
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.
