Albert Barnes Commentary Proverbs 12:4

"A worthy woman is the crown of her husband; But she that maketh ashamed is as rottenness in his bones." — Proverbs 12:4 (ASV)

Virtuous - The word implies the virtue of earnestness, or strength of character, rather than of simple chastity.

A crown - With the Jews the sign, not of kingly power only, but also of joy and gladness. Compare Song of Solomon 3:11.
