What is meant by this quote?

Question

Look thou but sweet,

And I am proof against their enmity.

Answer 1

Quote by William Shakespeare

"Alack! there lies more peril in thine eye

Than twenty of their swords: look thou but sweet,

And I am proof against their enmity."

It means: One sweet look from you could stop them from hating me.

"He means what was often said in the love poetry of the time, that an unfriendly glance from the eye of a lady could kill the man who was in love with her.  On the other hand, a sweet look from Juliet is all he needs to protect him from her kinsmen."
