What are some things Juliet says she will endure to stay romeos pure wife?

In Act IV Scene I she says:

O, bid me leap, rather than marry Paris,

From off the battlements of yonder tower;

Or walk in thievish ways; or bid me lurk

Where serpents are; chain me with roaring bears;

Or shut me nightly in a charnel-house,

O'er-cover'd quite with dead men's rattling bones,

With reeky shanks and yellow chapless skulls;

Or bid me go into a new-made grave

And hide me with a dead man in his shroud;

Things that, to hear them told, have made me tremble;

And I will do it without fear or doubt,

To live an unstain'd wife to my sweet love.

She says she is prepared to jump off a high tower, live the life of a thief, live in a snake-pit, be chained to a bear, or live in a crypt or a grave, all of which she says she is terribly afraid of. And in fact the Friar puts her to the test by taking her at her Word and making her face her fear of corpses by being buried alive.
