What it means

Look at the verse on the page: "Let them be yours alone, never to be shared with strangers." The "them" only makes sense if you back up a few verses. In Proverbs 5:15-16, the father has been using a picture: water from your own cistern, streams from your own well. He's not giving plumbing advice. He's talking about sex inside marriage. The "streams" and "waters" are the intimate life a husband and wife share — the desire, the body, the children, the whole shared current of a marriage.

So verse 17 is the punchline of that picture: keep that water to yourself. Don't let it run out into the street. Don't let "strangers" — anyone outside the covenant of your marriage — drink from what belongs only to your spouse. The Hebrew structure is emphatic: yours alone, full stop, and not for strangers with you. The "with you" stings a little — as if to say, you don't get to bring outsiders into something that was built for two.

Where does this sit in the book? Chapter 5 is one long fatherly warning against the zarah, the "strange woman" or adulteress (5:3-14). The father has just walked his son through the wreckage adultery leaves behind — ruined reputation, drained strength, regret that gnaws at the end of life. Then he pivots: instead of just saying "don't," he says "do — drink deeply from your own marriage." Verse 17 is the fence around that gift.

Christians have read this two ways, and both are fair. Most read it straightforwardly: a call to sexual fidelity in marriage. Others (like John Gill) hear an echo about guarding sound teaching from being mixed with "strange doctrines." The plain sense is the marital one; the spiritual application flows out of it.

Historical Context

Proverbs is traditionally tied to Solomon (roughly 970-930 BC), though the book as we have it was likely collected and edited over centuries, with final shape probably during or after the reign of Hezekiah (around 700 BC; see Proverbs 25:1). The form of chapters 1-9 is distinct: long fatherly speeches to a son. Think of a man sitting his teenage boy down before the boy leaves home for the city.

In ancient Israel, water was life. You didn't turn a tap. A family's cistern — a plastered pit that caught rainwater — or their well, dug down to groundwater, was guarded like treasure. Letting strangers help themselves to your water was unthinkable; it could mean your family went thirsty in the dry season. So when the father says "drink from your own cistern" and "don't share with strangers," every listener felt the weight in their gut. He's borrowing the most basic survival instinct they had — protect the water — and pressing it onto marriage.

The "strange woman" (Hebrew ishah zarah) the father has been warning about wasn't necessarily a foreigner. Zarah means "outsider" — outside your household, outside your covenant. She might be a neighbor's wife, a prostitute, or a woman whose husband was away on business (Proverbs 7:19). Israelite cities were small and tight; everyone knew everyone. Adultery wasn't just a private sin — it ripped a hole in the social fabric, broke inheritance lines, and was a capital offense under the Law of Moses (Leviticus 20:10).

The surrounding cultures — Canaanite, later Greek and Roman — were far looser. Temple prostitution was common at fertility shrines. The Hebrew father is teaching his son to live counter-culturally: in a world where sex was cheap and everywhere, guard the well.

Original Language

לְבַדֶּ֑ךָ (levaddekha) — "to yourself alone." The root bad means "separation, alone-ness." It's the same word used when God says it's not good for the man to be alone (Genesis 2:18). Here it flips: in marriage, your sexual life is meant to be alone with one person. Exclusivity isn't a cage — it's the shape of the gift.

זָרִ֣ים (zarim) — "strangers, outsiders." This is the masculine plural of the same root behind zarah, the "strange woman" of verse 3. The father is closing the loop: don't be the stranger in someone else's marriage, and don't let strangers into yours. Zar doesn't mean "foreigner from another country" — it means "anyone who doesn't belong inside this covenant." Your neighbor can be a zar to your marriage.

אִתָּֽךְ (ittakh) — "with you." A tiny word doing heavy lifting. The sin isn't just that strangers exist; it's that you bring them in alongside what was meant for two. Sexual sin is almost always a "with you" sin — the choice to make room at the table for someone who was never invited.

The cistern/fountain imagery (bor, בּוֹר, and be'er, בְּאֵר) matters too: one catches rain from above, one wells up from below. Marriage is both — gift from heaven and life from within.

Application

Here's what this verse is really asking you: what are you doing with your water?

The father in Proverbs is not embarrassed to talk about sex, and he's not squeamish about saying it has a fence around it. The fence isn't there because the thing inside is dirty. The fence is there because the thing inside is precious. You don't build a wall around a puddle. You build a wall around a well.

So ask honestly: where is your intimacy leaking? It might be the obvious — pornography, an emotional affair, a flirtation at work you've told yourself is "just friendship." But it might be subtler. The piece of yourself you give to a screen instead of your spouse. The vulnerability you pour out to a coworker that you've stopped pouring out at home. The fantasy life that has slowly replaced the real one. Every one of those is a stranger at your well.

And if you're not married — this verse still has your number. The water you're drawing now is the water you'll one day either bring into a marriage as a deep, clean well, or as a cistern that's been opened to half the neighborhood. The habits you build today are the marriage you'll have tomorrow.

The cost this verse asks of you is specific: cut off the strangers. Not "manage them better." Not "feel bad about them." Cut them off. Block the number. Delete the app. Have the hard conversation. Tell someone who will check on you next week.

And then — drink. Go home. Be present with the spouse God gave you. Or if you're single, give your heart fully to God and to the friendships He's actually put in front of you. The well is for drinking, not just for guarding.
