Every wise woman buildeth her house: but the foolish plucketh it down with her hands.
A wise woman will do what is needed for her family. She will seek ways to improve the home, the atmosphere and the physical needs of the family. Her goal is to make things better at home and the best way to do that is to be a keeper of the home.
A foolish woman will tear apart her household. She may not see the importance of diligent work and be lazy. She may not be careful of how she spends money. She may be seeking praise from man instead of knowing her value in God. In whatever case, her home, her family, will come to ruin if she puts her focus on things of this world rather than fearing the Lord.
