Not to many people of a strange speech and of an hard language, whose words thou canst not understand. Surely, had I sent thee to them, they would have hearkened unto thee.
ASV
not to many peoples of a strange speech and of a hard language, whose words thou canst not understand. Surely, if I sent thee to them, they would hearken unto thee.
