Shared ground
These verses present Wisdom speaking and tying outcomes to personal response. The text explicitly claims that “by me” a person’s days are multiplied and their years increase. It also explicitly states a personal-results principle: if someone becomes wise, the benefit comes back to that person; if someone chooses mocking, that person bears the resulting burden alone.
The passage assumes a moral order in which choices have fitting consequences. It does not frame wisdom as mainly social status or public applause; it portrays wisdom as personally beneficial (“for yourself”) and mocking as personally costly.
Where interpretation differs
Two questions commonly come up.
First, whether the “more days” language is a promise of literal longevity or a more general way of describing life going better (stability, fewer self-inflicted disasters, a fuller life).
Second, what exactly the mocker “bears”: some read it mainly as inner or social fallout (shame, ruined relationships, missed opportunities), while others hear a stronger note of penalty before God within the book’s moral vision.
Why the disagreement exists
Proverbs often states outcomes in brief, memorable lines rather than detailed explanations. That style can sound absolute even when the book elsewhere acknowledges complexity in life. Also, the images here (“increased years,” “bear it”) are broad enough to include more than one kind of consequence.
What this passage clearly contributes
Explicitly, it links Wisdom to life-increase language and sets out individual responsibility: the wise person receives the gain of wisdom, and the mocker carries the weight of mocking. As theological inference, many readers conclude that God’s ordered world generally makes wisdom life-giving and scorn self-damaging, even if the text itself does not spell out every mechanism or exception. In context, this builds on the chapter’s two invitations (Wisdom vs. Folly) and clarifies that the chooser cannot offload the outcome onto others (compare Proverbs 9:10).
