YHWH tears down the house of the proud but maintains the widow's boundaries.
Proverbs 15:25

The house of the proud might not be torn down in his lifetime, but the house is more than the man. See Ahab, Achan, and the Canaanites. The difference between the proud and the widow is that the proud has a house, which means he has children and his name appears to carry on. The widow has no name of her own, and her children carry her husband's, not hers. The proud are those who would take what little she has, but God is the champion of the poor and defenseless.
