Few financial topics receive sharper warnings in Scripture than cosigning — putting your name on someone else's debt.
Proverbs returns to it again and again: "Be not one of those who give pledges, who put up security for debts" (Proverbs 22:26). The Hebrew word arav ("to pledge, become surety") appears in five separate Proverbs warnings.
This guide walks every passage, explains the historical practice, addresses the hard family situations. Gives a clear biblical framework for saying no to cosigning. Even for people you love.

The Hebrew word: arav
Hebrew arav (עָרַב) — "to pledge, exchange, become surety". Is the exact word translated "put up security" in Proverbs 6:1, 11:15, 17:18, 22:26. 27:13. The verb implies more than emotional support. It is legally and financially binding.
In ancient Israel, surety meant the cosigner's actual property. Clothing, livestock, even the bed they slept in (Prov 22:27). Could be seized by the lender if the borrower defaulted.
The five Proverbs warnings
- Proverbs 6:1-5 — "if you have put up security for your neighbor, have given your pledge for a stranger, if you are snared in the words of your mouth… do this then, my son, and save yourself: go, hasten, and plead urgently with your neighbor."
- Proverbs 11:15 — "Whoever puts up security for a stranger will surely suffer harm, but he who hates striking hands in pledge is secure."
- Proverbs 17:18 — "One who lacks sense gives a pledge and puts up security in the presence of his neighbor."
- Proverbs 22:26-27 — "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?"
- Proverbs 27:13 — "Take a man's garment when he has put up security for a stranger."
Why Scripture is so emphatic
- You take on the risk without the benefit — you owe the money, but you don't get the car/house/loan.
- You become "slave of the lender" for someone else's debt (Proverbs 22:7).
- It damages relationships — most cosigning ends in either default or resentment.
- It enables unwise borrowing — if no one would lend to them on their own, that's information.
- It violates Romans 13:8 — "owe no one anything except to love."
- Statistics confirm — the FTC estimates 75% of cosigned loans default to the cosigner.
The hard cases: family
- Adult child wants a car — give a smaller amount as gift toward a used car they can afford alone.
- Parent needs help with mortgage — gift money directly if you can; do not cosign a 30-year liability.
- Sibling starting a business — invest as equity (you own a share) or gift; never cosign.
- Spouse with bad credit — joint applications are different from cosigning; consult a Christian financial advisor.
- The principle — give what you can afford to lose. Never sign for what would devastate you if it defaulted.
How to say no graciously
- Tell them upfront: "I love you and I won't cosign — Proverbs 22:26-27 has been formative for me. Here is what I can do…"
- Offer the smaller help you can give as a gift, not a loan.
- Help them improve their credit instead — share resources, mentor budgeting.
- Pray with and for them about the underlying need.
- Recommend they delay the purchase rather than rush via cosigning.
If you have already cosigned
Proverbs 6:1-5 gives the Bible's only response: "go, hasten, and plead urgently." Talk to the borrower. Talk to the lender.
See if you can be released, refinanced off the loan, or have the borrower buy the asset back into their name. Track payments monthly. Save aggressively to be ready if you have to pay it.
Do not assume "they'll handle it" — they often won't.
