My humble opinion is that the description was given to a man, and shows what men naturally look for in a woman, especially one that is going to cost a handsome dowry. The description of a never-tiring, ever-glowing, and kind-speaking woman are qualities which men naturally look for. Verse 30 points to the quintessential quality men should seek in a life-partner: "favour is deceitful, and beauty is vain: but a woman that feareth the Lord, she shall be praised."
