Genesis 3:24

So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.

1. The LORD God drove Adam and Eve out of the garden.
2. The tree of life was apparently located at the east end of the garden of Eden.
3. The LORD God apparently placed Cherubims and a flaming sword (that turned every way) near the tree of life to prevent Adam and Eve from eating from it.
4. Cherubims, whatever they were, apparently had the power to prevent Adam and Eve from eating from the tree of life.
5. The LORD God may employ sophisticated technology to accomplish His objectives (what in the world is a flaming sword that turns every way - it sounds like an automatic light sabre).
