Five times in Proverbs — 6:1-5, 11:15, 17:18, 20:16, 22:26-27 — Solomon warns against putting your hand under another person's debt. The Hebrew arav ('to pledge, to give one's hand') names what we now call co-signing or guaranteeing a loan. Every surety passage in Scripture is a warning. None recommend it. This study walks every text, the ancient handshake practice, and a six-rule framework for the modern co-signing decision.
Proverbs 6:1-5 — the escape commands
'My son, if you have put up security (aravta) for your neighbor, have given your pledge for a stranger, if you are snared in the words of your mouth, caught in the words of your mouth, then do this, my son, and save yourself, for you have come into the hand of your neighbor: go, hasten, and plead urgently with your neighbor. Give your eyes no sleep and your eyelids no slumber; save yourself like a gazelle from the hand of the hunter, like a bird from the hand of the fowler.'
The intensity of the language is the point. The escape commands are emergency commands — 'do not sleep until you are out of this.' The verb aravta ('you have pledged') puts the borrower's risk on the guarantor. Solomon's counsel: get out, immediately, by whatever moral means.
Proverbs 11:15 — the harm is certain
'Whoever puts up security for a stranger will surely suffer harm, but he who hates striking hands in pledge (toqei tāqaʿ) is secure.' The Hebrew tāqaʿ kaf ('to strike the palm') is the ancient handshake that bound a co-signer — the legal-binding gesture, like a modern signature. Solomon does not say 'might suffer'; he says ra-yeroaʿ, 'will surely be broken/harmed.' The verb is intensive.
Proverbs 17:18 — the lack of sense
'One who lacks sense gives a pledge and puts up security in the presence of his neighbor.' The Hebrew adam chasar-lev — 'a person lacking heart/sense.' The Hebrew lev ('heart') is the seat of judgment, not emotion. To co-sign, in Solomon's verdict, is to lack the basic faculty for sound judgment.
Proverbs 20:16 and 27:13 — take his garment
'Take a man's garment when he has put up security for a stranger, and hold it in pledge when he puts up security for foreigners.' Solomon's counsel to the lender: if your borrower has co-signed for a stranger, demand harder collateral. The borrower's act of guaranteeing someone else's debt makes him a higher credit risk to you. The proverb confirms how Solomon views surety — as a structural increase in financial fragility.
Proverbs 22:26-27 — the bed beneath you
'Be not one of those who give pledges, who put up security for debts. If you have nothing with which to pay, why should your bed be taken from under you?' The picture is the creditor seizing the guarantor's basic possessions when the original borrower defaults. The 'bed' (mishkav) is the last asset — the warning is that surety can take from you what you cannot replace.
The Hebrew vocabulary
Two roots organize the topic. Arav (ערב) — to pledge, to give as security, to stand surety for. The noun arubbah means a pledge or guarantee. Tāqaʿ kaf (תָּקַע כָּף) — to strike the palm — the ancient handshake that bound the guarantor legally. The combined picture: a person gives their hand as the legal pledge that, if the borrower defaults, the guarantor will pay.
The same verb arav appears in Genesis 43:9 (Judah pledging himself for Benjamin's safe return) and Genesis 44:32 — these are the only positive uses, and they are a brother pledging his own person for a brother's safety, not financial co-signing.
A six-rule framework for the modern co-signing decision
- Default no. Every proverb on surety is a warning. The biblical default is decline; the exception requires a powerful reason.
- If you cannot afford to pay it in full today, do not co-sign. Treat the obligation as if you have already paid it. If that ruins you, refuse.
- Never co-sign for someone who would not lend to you in the same situation. The reciprocity test exposes the relational reality.
- Refuse to co-sign on cars, credit cards, and consumer debt — every time. These are the highest-default categories.
- If you must help, give the money instead of guaranteeing the loan. A gift you can absorb is healthier than a pledge you may not be able to.
- If you have already co-signed, execute Proverbs 6:1-5. Talk to the borrower urgently. Refinance to remove yourself. Pay off the debt early. Do not sleep until you are out.
