'Ah!' said Antonio, 'I am the unhappy cause of these quarrels.'

Portia bid Antonio not to grieve at that, for that he was welcome
notwithstanding; and then Antonio said: 'I once did lend my body for
Bassanio's sake; and but for him to whom your husband gave the ring,
I should have now been dead. I dare be bound again, my soul upon the
forfeit, your lord will never more break his faith with you.' 'Then you
shall be his surety,' said Portia; 'give him this ring, and bid him keep it
better than the other.'

When Bassanio looked at this ring, he was strangely surprised to find
it was the same he gave away; and then Portia told him how she was
the young counsellor, and Nerissa was her clerk; and Bassanio found,
to his unspeakable wonder and delight, that it was by the noble
courage and wisdom of his wife that Antonio's life was saved.

And Portia again welcomed Antonio, and gave him letters which by
some chance had fallen into her hands, which contained an account of
Antonio's ships, that were supposed lost, being safely arrived in the
harbour. So these tragical beginnings of this rich merchant's story
were all forgotten in the unexpected good fortune which ensued; and
there was leisure to laugh at the comical adventure of the rings, and
the husbands that did not know their own wives Gratiano merrily
swearing, in a sort of rhyming speech, that

. . . while he lived, he'd fear no other thing
So sore, as keeping safe Nerissa's ring.
