Quick answer
A wife is a find, a good one, and behind the finding stands the LORD's favor. The verse celebrates marriage as gift rather than achievement.
Read both lines
The first line uses treasure vocabulary: finding, discovery, coming upon something valuable, and the book later prices the find above rubies (31:10). Its companion completes the economics: houses and riches are inherited from fathers, "but a prudent wife is from the LORD" (19:14). The second line names the source: favor received as gift, which quietly reframes every good marriage; what looks like luck from the outside is, at bottom, given. Nothing here turns marriage into a merit badge or singleness into a deficiency; this is a proverb about where good things come from, not a ranking of lives. Its practical edge points at husbands first: a man persuaded that his wife is favor from the LORD handles her accordingly.
