Genesis chapter 2 verse 16-17

Genesis chapter 2 verse 16-17 is;The Lord commanded the man,you can eat from any tree in the garden but, you may not eat from the tree from the knowledge of good & evil.It maens that God gave only 1 rule to Adam & Eve but did they listen not at all.I like this verse because its good to know what happened in the old testemant starting with Genesis.
