This proverb echoes Proverbs 20:16 — the financial wisdom of requiring collateral when someone has made a reckless guarantee for an unknown person. Co-signing for a stranger is imprudent; the person who does so has taken a serious risk. The text is a practical warning about financial entanglement with the untrustworthy. Wisdom in money matters is part of godly stewardship.
Memory phrase: Be wise with promises and money.
Talk about it: Why is it risky to promise to pay someone else's debt when you do not know them well?
Prayer: God, help me be wise and careful with every promise I make.
