More than anything else, the fact that your 
unwavering hard work has been rewarded
الأهمّ من أيّ شيء آخر، حقيقة أنّ عملكما
الدّؤوب الرّاسخ قد أُجزي
Me alegra que su duro trabajo
tenga su recompensa.
Me alegra que vuestro duro trabajo
tenga su recompensa.
Plus que tout le reste,
je suis content que vos efforts
Quel che mi rende felice
 è che il vostro inesauribile duro lavoro
Mais do que tudo, fico feliz de ver que sua
dedicação inabalável tenha gerado frutos.
