Above all things, be not made an ass to carry the burdens of other men if any friend desire thee to be his surety, give him a part of what thou has to spare if he presses thee further, he is not thy friend at all.
Walter RaleighIf 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.
Walter Raleigh
