Perhaps it wasn't you I have gone over this before, how Origen (184-253), an early Church Father, who recommended starting with the Book of Revelation and looking for the spiritual teachings behind all the myths, allegories, horror stories in the Bible. He used the example of the ban on the Amalekites, where everything in that town was to be destroyed, men, women, children, the best of the livestock...everything. If you are familiar with the story, we see that King Saul did not follow this ban--he kept a little of this, and some of that, right down to the king, the leader of the Amalekites. The prophet Samuel was furious when he arrived, and he, himself, hacked the Amalekite king into pieces.
Origen, pointed out the story is about what we, as average human beings, decide to keep what is rich, pleasurable, valuable in our own lives that prevent us from being holy and good. Instead of banning all that is evil from our lives, we keep some of this, a little of that to play around with because...what real harm can a little do? Take a look at future events...Amalekites began taking over again, just as a little sin can take over more and more of our own lives.
