3 But I am afraid that as the serpent deceived Eve by his cunning, your thoughts will be led astray from a sincere and pure devotion to Christ.
Genesis 3
1 Now the serpent was more crafty than any other beast of the field that the LORD God had made. He said to the woman, “Did God actually say, ‘You shall not eat of any tree in the garden’?”2 And the woman said to the serpent, “We may eat of the fruit of the trees in the garden,3 but God said, ‘You shall not eat of the fruit of the tree that is in the midst of the garden, neither shall you touch it, lest you die.’”4 But the serpent said to the woman, “You will not surely die.5 For God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil.”
Revelation 12
9 And the great dragon was thrown down, that ancient serpent, who is called the devil and Satan, the deceiver of the whole world—he was thrown down to the earth, and his angels were thrown down with him.
