Which excerpt from “Paul Revere's Ride” supports the theme that heroes help people in times of danger?

“Then he said "Good-night!" and with muffled oar
Silently rowed to the Charlestown shore,”
“In the hour of darkness and peril and need,
The people will waken and listen to hear”
“Hardly a man is now alive
Who remembers that famous day and year.”
“Meanwhile, his friend through alley and street
Wanders and watches, with eager ears”
