So, Hebrew poetry is big on parallelism.
Say something once, then say it again another way.
So, Proverbs 31:10
An excellent wife who can find?
She is far more precious than jewels.
And given that "more precious than jewels" is the Proverbs way of talking about Wisdom (3:15, 8:11) this is a way of saying that the excellent wife is found when wisdom is found. And therefore, as previously blogged here - not ultimately about finding a spouse for yourself. The rest of the acrostic poem / riddle in Proverbs 31 point us in the same direction - much to learn about marriage but ultimately looking to the most excellent bride and her glorious husband...
Or take the famously half-read Proverbs 29:18
"Where there is no vision, the people perish:
but he that keepeth the law, happy is he" KJV
Which isn't about general vision but, prophetic vision.
Where God's word is found - via prophets and supremely in Scriptures...
"Where there is no prophetic vision the people cast off restraint,
but blessed is he who keeps the law" ESV
The parallelism helps us know where to find vision. When people don't have the word of God they're ruined (like God's people casting off restraint to make and worship a golden calf in Exodus 32, perhaps?), but when they stick with God's word they'll know God's blessing. The law here being what God had said... law, prophetic vision,... words for the same thing: the word of God, today in Scripture and in weighed & tested prophecy.
And so what of Proverbs 29:18. It's not a leadership manual inspiring half-a-proverb, but a call for God's people to live by the word of God... and therefore to be a theocentric people (loving Christ our Wisdom) since the alternative is that we rule ourselves and are ruined (as lovers of folly). Mmm, tasty gospel words in Hebrew poetry.
With thanks to Peter Mead for reminding me how poetry works.
