Act 3 Scene 2: Bassanio comes to take part in the lottery and he chooses the correct casket. Portia gives him a ring too.
"It is endangered in the eyes, with gazing fed, and fancy dies in the cradle where it lies."
"But when this ring parts from this finger, then parts life from hence - O then be bold to say Bassanio's dead!"
"if thou dost shed one drop of Christian blood, thy lands and goods are by the laws of Venice confiscate unto the state of Venice.
"I would have my bond!!"
Act 4 Scene 1: The court trial begins. Portia is dressed as the judge in this trial. Eventually, Shylock loses and his lands and goods are confiscated. Gratiano and Bassanio give the rings they swore to keep for their wives to the judge and clerk, but they did not know they were actually them.
"I would lose all, ay, sacrifice them all here to this devil, to deliver you"
"I do oppose my patience to his fury, and am armed to suffer with quietness of spirit"
"Sweet lady, you have given me life and living; for here I read for certain that my ships are safely come to road"
Act 5 Scene 1: Antonio is introduced to Portia. Gratiano and Nerissa argue about the rings. Bassanio still has to confess to Portia about the ring too. Eventually, Portia and Nerissa tells them they were actually the clerk and judge. Lorenzo and Jessica are happy. In the end, Gratiano and Nerissa forgive each other. Antonio's ships are safely at harbour too.
"You swore to me when I did give it to you that you would wear it till your hour of death and that it should lie with you in your grave"
"Sir, you are welcome to our house: it must appear in other ways than words, therefore I scant this breathing courtesy."
"Give welcome to my friend - This is the man, this is Antonio, to whom I am infinitely bound."
