Proverbs 12:9 is a little muddled to me. I do find a couple of commentaries in my Logos Bible Software that agree that it’s a bit muddled. The main view appears to be this: better to have a small reputation and be independent than to be famous and starve. It’s not about being wrongly esteemed, but about being less than famous. There is the possibility of a vowel redistribution, as in a few other Hebrew places, which would make this Proverb reflect that it is better to work for yourself, to be your own servant.
Either way, I think we can apply this to the idea of not trying to live large and get famous. It’s better to do what you do, and let fame happen if it does.
Proverbs 12:19 comes again to honesty and integrity. By now, and we’re not even halfway through Proverbs, we should all know that honesty is better. Lies do not last. End of story.
