I put these kids in danger for 
the sake of the promise I made,
عرّضت هؤلاء الأولاد للخطر 
،من أجل الوعد الّذي قطعت
Ich hab die Kinder für mein
Versprechen in Gefahr gebracht.
Aunque los puse en peligro
por la promesa que hice,
Aunque los puse en peligro
por la promesa que hice,
Pour tenir cette satanée promesse,
Ho coinvolto dei ragazzi per mantenere
la promessa fatta ai miei compagni
Eu envolvi essas crianças pra poder cumprir
a promessa com meus companheiros,
Ради обещания друзьям
