Satan

Now the serpent was more subtle than any animal of the field which Yahweh God had made. He said to the woman, “Has God really said, ‘You shall not eat of any tree of the garden?’”
The serpent said to the woman, “You won’t surely die,
for God knows that in the day you eat it, your eyes will be opened, and you will be like God, knowing good and evil.”
Yahweh God said to the serpent, “Because you have done this, you are cursed above all livestock, and above every animal of the field. On your belly you shall go, and you shall eat dust all the days of your life.
Angels who didn’t keep their first domain, but deserted their own dwelling place, he has kept in everlasting bonds under darkness for the judgment of the great day.
