Shared ground
These lines use everyday water imagery—cistern, well, springs, streams—to portray desire being satisfied from a protected, rightful source (v.15). The rhetorical question about water spilling into streets and public squares assumes the answer “no” (v.16). The closing line states the point in plain terms: what is pictured by these “waters” is meant to be exclusive (“for yourself alone”) and not shared with “strangers” () who are “with you” (v.17).
In the wider flow of Proverbs 5, this picture functions as a positive alternative within a warning against illicit intimacy. The text’s explicit claims are about exclusivity, boundaries, and not letting what should be protected become publicly spread.
Where interpretation differs
Some readers take the water picture as a direct metaphor for sexual intimacy within marriage. Others think it can include broader household goods—one’s resources, family stability, or the “fruit” of one’s life—while still fitting the chapter’s sexual warning.
Another difference concerns v.16: “overflow in the streets” may be read mainly as promiscuity (sharing intimacy widely), or as the wider consequences of illicit sex becoming public—loss of privacy, reputation damage, and social fallout.
A smaller question is how to hear “for yourself alone” (v.17). Many understand it as spouse-exclusive access. Others stress that the phrase is about excluding outsiders (“strangers”), not denying that marriage has shared outcomes (like children), since the focus of the line is who is not included.
Why the disagreement exists
The passage speaks through an extended picture rather than naming sex directly in these three verses. That leaves room for debate about how tightly each detail maps onto sexuality versus the spillover effects on one’s household and public life.
What this passage clearly contributes
These verses add a clear wisdom theme: desire is meant to be satisfied within protected boundaries rather than dispersed into public, uncontrolled space. Explicitly, the teacher calls for an exclusive “yours” and denies sharing it with outsiders (vv.15, 17), using the “street/public squares” contrast to underline how misdirected intimacy becomes exposed and spread (v.16).
