You’ve gotta check out this blog post by Dan Phillips at Pyromaniacs. He walks through Proverbs 6:1-19, showing how his understanding of the text unfolded as he observed more and more carefully. He noticed the structure, and the way the passage hangs together around the three progressively bad kinds of fool.
And his careful observation leads him to many of the same conclusions I drew about this text and these three kinds of fool.
I highly recommend it, if you’re up for a fun journey. Check it out!
