C.N. Douglas, comp. Forty Thousand Quotations: Prose and Poetical. 1917.
Beware of suretyship for thy best friend. He that payeth another mans debt seeketh his own decay. But if thou canst not otherwise choose, rather lend thy money thyself upon good bonds, although thou borrow it; so shalt thou secure thyself, and pleasure thy friend.
If any friend desire thee to be his surety, give him a part of what thou hast to spare; if he press thee further, he is not thy friend at all, for friendship rather chooseth harm to itself than offereth it. If thou be bound for a stranger, thou art a fool; if for a merchant, thou puttest thy estate to learn to swim.
Such as are betrayed by their easy nature to be ordinary security for their friends leave so little to themselves, as their liberty remains ever after arbitrary at the will of others; experience having recorded many, whom their fathers had left elbow-room enough, that by suretyship have expired in a dungeon.
