If thou hast nothing to pay, why should he take away thy bed from under thee?
– Proverbs 22:27
[B]eing surety, or striking hands, is like cosigning a loan for someone today. If the borrower defaults, the cosigner assumes responsibility for the debt. The warning of the previous verse comes home in harsh reality that you could literally lose your bed from under you. Wisdom takes a longer view and looks to the outcomes, or the end of the way you are going. Becoming surety opens yourself to vulnerability and puts you at risk of future loss.
