Genesis 3:1

Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?

1. Noted: the word "subtil" is an archaic spelling of "subtle".
2. A serpent spoke to the woman, asking her a question.
3. The serpent was the most shrewd and cunning of all the animals created.
4. The LORD God created the serpent.
5. The serpent knew what the LORD God had told the man and woman, and was able to quote it.
6. This serpent was obviously different from the snakes we know of today. I'm not aware of any who have language skills or vocal cords.
7. There was a snake in the garden, so it wasn't the ideal place to live.
