Genesis 3:1, 24

The serpent was the shrewdest of all the wild animals the LORD God had made. One day he asked the woman, “Did God really say you must not eat the fruit from any of the trees in the garden?”

After sending them out, the LORD God stationed mighty cherubim to the east of the Garden of Eden. And he placed a flaming sword that flashed back and forth to guard the way to the tree of life.
