Adam Clarke on Proverbs 31:27

She looketh well to the ways of her household -

18. She is a moral manager: she takes care that all shall behave themselves well; that none of them shall keep bad company or contract vicious habits. A religious industry, or an industrious religion, is the law of her house. She can instruct them in religion, as well as she can teach them in their labor. In her house, diligence in business, and fervency of spirit, serving the Lord, go hand in hand.

And eateth not the bread of idleness -

19. She knows that idleness leads to vice; and therefore every one has his work, and every one has his proper food. That they may work well, they are fed well; and every one, at least, earns the bread that he eats - eateth not the bread of idleness.
