Julius caesar by william shakespeare

which passage from julius caesar act 4 uses a metaphor?

for shame, you generals! what do you mean? / love, and be friends, as two such men should be, / for i have seen more years, i’m sure, than ye.

of your philosophy you make no use, / if you give place to accidental evils.

ever note, lucilius, / when love begins to sicken and decay / it useth an enforced ceremony.

you wrong me every way; you wrong me, brutus; / i said, an elder soldier, not a better. / did i say “better”?

i thought the second one, but my brother told me it was wrong but he did not know which one was the right one.
