What event do benvolio's lines from the opening of act iii, scene i of romeo and juliet, hint at, or foreshadow

Benvolio's lines from the opening of Act III, Scene I of Romeo and Juliet, suggest that in that scenario Benvolio and Mercury can meet with the capulets and that encounter can generate a fight between them.

Here below is the opening of Act III, which proves what I said above:

"BENVOLIO : I pray thee, good Mercutio, let’s retire.  The day is hot; the Capulets, abroad;  And if we meet we shall not ’scape a brawl,  For now, these hot days, is the mad blood stirring."

this passage has a lot of figurative language like examples are

the day we found the sharks' teeth was foggy and cool.

moisture hung in the air so thick you could almost see it sparkling in the dim sunlight.

figurative language can not be taken seriously it is just sayings.

nautre

nature is sure to be the best thing on earth

the sunshine and beauty is sure to be worth

this can't be sold

for any money or gold

because nature is strongly beautiful and is the best thing to happen on earth
