WILL MARK BRAINLIEST

Knew you not Pompey? Many a time and oft
Have you climb'd up to walls and battlements,
To towers and windows, yea, to chimney-tops,
Your infants in your arms, and there have sat
The livelong day, with patient expectation,
To see great Pompey pass the streets of Rome:
And when you saw his chariot but appear,
Have you not made an universal shout,
That Tiber trembled underneath her banks,
To hear the replication of your sounds
Made in her concave shores?

The word in bold (first Pompey) refers to

a river
a general
an echo
a pause
