Quote #4
DUKE, as FriarThis being granted in course, and
now follows all: we shall advise this wronged maid
to stead up your appointment, go in your place. If
the encounter acknowledge itself hereafter, it may
compel him to her recompense; and here, by this, is
your brother saved, your honor untainted, the poor
Mariana advantaged, and the corrupt deputy
scaled. (3.1.275-282)
When the Duke devises a bed trick (when one sexual partner is secretly substituted for another) that will deceive Angelo into having sex with Mariana, he reasons that, once Angelo sleeps with his ex-fiancé, he'll have to marry her.
This literary devise is a favorite of Shakespeare's, who also uses it in All's Well That Ends Well, where Bertram is duped into sleeping with Helena. In both Measure for Measure and All's Well, the bed trick is geared toward securing heterosexual marriage.

My lord, this is one Lucio's information
against me. Mistress Kate Keepdown was
with child by him in the Duke's time; he promised
her marriage. His child is a year and a quarter old
come Philip and Jacob. I have kept it myself, and see
how he goes about to abuse me. (3.2.199-204)
Here, we learn that Lucio has jilted Kate Keepdown, the mother of his child. Why did Lucio break his promise to marry Kate? Keep reading....
Quote #6
LUCIO
I beseech your Highness do not marry me to a
whore. Your Highness said even now, I made you a
duke. Good my lord, do not recompense me in
making me a cuckold. (5.1.588-591)
Lucio declares that marrying a prostitute is a fate worse than torture because being hitched to a promiscuous woman will make him a "cuckold" (a man cheated on by his wife). (Apparently, it's OK for him to have sex with Kate, but Lucio wouldn't deign to marry her.) Lucio feels that marriage to a "whore" will compromise his masculinity and destroy his life.
