If my voice were louder,
If my body stronger,
I would tear through the streets,
Crying
Peace,Peace,Peace

Wenn ich nur Kraft hätte
Ich liefe auf die Strasse
Und würde schreien nach Frieden
Frieden Frieden Frieden

Были б силы в теле,
Был бы голос громче,
Я бы бежал по миру
С криком мир, мир, мир!

Se a voz me deixasse,
S’eu tivesse mais forças,
Eu sairia gritando
Paz, Paz, Paz

If I were to have enough strength,?
I would run around in the streets,
and I would scream out:
Shabbos, holy Shabbos!
Shabbos, Shabbos, holy Shabbos!
Shabbos, Shabbos, holy Shabbos!
Shabbos is the day of God
