do you promise to protect her as you would
your own country with unwavering faith?
هل تعِدُ بأن تحميها كما تحمي بلدك بإيمان راسخ؟
alle Leibeskräfte für sie aufzubringen,
um sie und das Reich zu beschützen?
pour la protéger, elle et son pays,
di dedicarti con forza immutata
alla protezione sua e del suo regno?
proteger e dar apoio para ela e sua nação?
что будешь беречь её саму и её земли
с неиссякаемым усердием?
