This verse closes Wisdom's banquet, Proverbs 9:1–6.
Quick answer
The one thing asked of the guest: leave the old company and walk a different road. Not qualify, not improve. Come.
Read the whole unit
Collection I ends the way a well-built argument ends, by putting the whole thing in one picture. Two women have set two tables. Both are in the same city, both call from its highest places, and both are calling the same people. One of them is Wisdom, and this is her half.
She builds first. Verses 1 and 2 are a run of finished work: a house built, pillars hewn, meat slaughtered, wine mixed, the table set. Nothing about her offer is improvised, and nothing about it is cheap; a household that slaughters an animal and mixes wine is putting on the best it has. Only then does she send out her servants and start calling.
Who she calls is the point. Not the wise, not the accomplished, not the qualified: "whoever is simple," and the one who "lacks understanding," which the Hebrew puts as lacking heart. Those are the two least promising categories in the book, and they are the only two she names. The invitation goes to the people with the least to bring.
A note on the chapter's design that matters for reading either half. Wisdom's invitation in verse 4 and Folly's invitation in verse 16 are, in Hebrew, the same sentence. Word for word, apart from two small connecting words. Both women stand at the high point of the city, both address the simple and the one lacking heart, and both say turn in here. The chapter is built to make that overlap unmissable, and the reason is the honest one: from the street, the two invitations sound alike. What separates them is not the volume, the warmth, or the wording. It is what is actually on the table and where the guests end up, and neither of those is visible from the road.
That is why the chapter gives Wisdom the whole preparation sequence before she says a word. She has something to serve. The test the reader is being handed is not "which voice sounds more appealing" but "which one has built a house."
What this verse contributes
This verse gives the invitation its single condition, and the condition is departure rather than achievement. "Forsake foolishness" is about what a person walks away from, and the promise attached to it, "and live," is the same word the book has been using since chapter 4 for a life that actually goes somewhere. Notice the order across these six verses: she builds, she prepares, she sends, she calls, she serves, and only then does she ask for anything. Nothing was required of the guest to get the table laid.
From this side of the cross
Wisdom's method here has a long echo. She prepares a feast at her own expense, sends servants into the city, and calls the people with nothing to bring. Isaiah puts the same offer in the same shape: "Everyone who thirsts, come to the waters; and you who have no money, come, buy and eat... without money and without price" (55:1). And Jesus told a story about a supper where the invited made excuses and the master sent his servant into the streets and lanes to bring in the poor, the maimed, the lame, and the blind, and then further out to the highways and hedges until the house was full (Luke 14:16–23). Proverbs is not predicting that. It is describing how wisdom conducts herself, and it turns out that God conducts Himself the same way, further out and at greater cost than a proverb could have said.
