A foolish woman; by which he understands, either,
1. Folly, which is opposite to that wisdom of which he hath been so long discoursing; and so it may include all wickedness, either in principle, as idolatry, heresy, &c., or in practice. Or,
2. The harlot; which, with submission, seems most probable to me, partly because all the following description exactly agrees to her, especially what is said Proverbs 9:17, as also Proverbs 9:18, which in effect was said of the harlot before, Proverbs 2:18, Proverbs 5:5; and partly because such transitions from discoursing of wisdom, to a discourse of harlots, are frequent in Solomon, as we have seen, Proverbs 2:16, Proverbs 5:3 7:5. Is clamorous; speaks loudly, that she may be heard; and vehemently, that persons might be moved by her persuasions. Knoweth nothing; to wit, aright, nothing that is good, nothing for her good, though she be subtle in little artifices for her own wicked ends.
