A virtuous wife is excellent in character and deeds because she is a trophy of divine grace. Her loving support and competent fulfillment of responsibilities make her a precious treasure for her husband. Her good qualities often supply that which her husband is lacking, thus crowning him with a nobility he would otherwise not have had (Proverbs 31:10–31).
However, a wife with sinful habits, such as foolishness, laziness, vanity, wildness, perversity and indiscretion, not only shames her husband in public, but also weakens him in himself. Here is a call for wives to nurture godly qualities, and for their husbands to esteem and love them accordingly.
4 An excellent wife is the crown of her husband, but she who brings shame is like rottenness in his bones.
