Are those shouts of joy coming 
from the people they oppressed?
هل صيحات الفرح هذه
صادرة من الشعب الذي اضطهدوه؟
Sind diese Stimmen die Siegesrufe
des unterdrückten Fußvolks?
Se oye la victoria del pueblo
que resurge aunque lo pisen.
Se oye la victoria del pueblo
que resurge aunque lo pisoteen.
Le brouhaha ambiant
est le cri de victoire du peuple.
Quelle grida di vittoria vengono
dal popolo un tempo oppresso!
Já se ouve o burburinho do povo que
ressurge mesmo depois de ser pisado.
Но кто же шумит так радостно?
Неужто народ, который угнетали?!
