What is the meaning behind the soliloquy in act 3 scene 2 lines 17-33 in Romeo and Juliet?Act 3 scene 2 lines 17-33Come, gentle night, come,...

As Romeo and Juliet are married between Acts 2 and 3,
Juliet anxiously awaits their wedding night in Act 3, scene 2.  The lines you're
referencing occur at the beginning of the scene; in them, Juliet describes the
impatience she feels waiting for Romeo. 

In lines 17-23,
Juliet comments on Romeo's allure and says that when he's dead, and if he's cut into
"little stars," he'll make the night so beautiful that no one will want it to be
daytime.  (Of interest is the pronoun used in line 18.  In early editions of the play,
the line read "when I shall die," and text with this edition often footnote that Juliet
might mean that when she's dead she'll share Romeo's beauty with the world.  The pronoun
was changed from "I" to "he" in the Fourth Quarto.)

In the
rest of the lines you list, Juliet uses figurative language to describe the impatience
she feels while waiting for Romeo.  She comares her impatience to the eagerness of a
child who has new clothes but is not yet allowed to wear them, and she likens her new
(but not yet consummated) marriage to Romeo to a "mansion of a love" which she has
bought but not yet "possessed."

Finally, when Juliet sees
the Nurse returning, she remarks that any news containing Romeo's name is
"heavenly." 

Again, these lines all show how eager Juliet
is to see Romeo.
