Proverbs 9:3 - Joseph Benson’s Commentary on the Old and New Testaments

She hath sent forth her maidens Her servants, to invite the guests, namely, the ministers of the word of God, whom he calls maidens, for the decency of the parable; for Wisdom being compared to a great princess, it was fit she should be attended on by maidens. She crieth upon the highest places Upon the tops of the houses, (which were flat,) conformably to what our Lord says, Matthew 10:7, What ye hear in the ear, that preach ye upon the housetops. Or, from such high seats and places as those from which judges delivered their sentences, and officers made proclamations for the convenience of the people's better hearing.
