This verse sits inside Wisdom's banquet, Proverbs 9:1–6.
Quick answer
The invitation goes out, and it goes out twice over: servants sent into the city, and her own voice from the high ground.
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 moves the banquet from the house to the streets, and the doubling is deliberate. She does not wait to be found; she sends, and she also calls. The location, the highest places of the city, is the same phrase that will describe where Folly sits in verse 14, which is the first of several deliberate overlaps between the two halves. What separates them here is motion. Wisdom sends servants out into the city. Folly, when we meet her, will be sitting down.
