Take his garment when he has put up security for a stranger,
and if it is for foreigners, hold him as security. Bible see other translations

Guaranteeing a loan for another person who cannot afford to guarantee the loan himself is so risky that it is like the loan has been defaulted already. Thus, if a person guarantees a loan, often using his overcoat as security, the person who gave the loan should just take the coat at the start.
