Which two lines in this excerpt from shakespeare's romeo and juliet forshadow the tragic fate of romeo and juliet?

ROMEO: Amen, amen! but come what sorrow can,

It cannot countervail the exchange of joy

That one short minute gives me in her sight:

Do thou but close our hands with holy words,

Then love-devouring death do what he dare;

It is enough I may but call her mine.

FRIAR LAURENCE: These violent delights have violent ends

And in their triumph die, like fire and powder,

Which as they kiss consume: the sweetest honey

Is loathsome in his own deliciousness

And in the taste confounds the appetite:

Therefore love moderately; long love doth so;

Too swift arrives as tardy as too slow.

600 grams is the answer
