Charles Ellicott Commentary Proverbs 9:4

"Whoso is simple, let him turn in hither: As for him that is void of understanding, she saith to him," — Proverbs 9:4 (ASV)

Whoever is simple ... as for him that lacks understanding— So God does not call many wise men after the flesh, not many mighty, not many noble (1 Corinthians 1:26); but chooses the foolish, weak, and base, whom people might overlook; not being willing that any should perish (2 Peter 3:9), especially His little ones (Matthew 18:14), who are liable to fall through their inexperience and lack of judgment.
