Parallel
Ezekiel 3:6
Brenton's English Septuagint · Berean Standard Bible
neither to many nations of other speech and other tongues, nor of harsh language, whose words thou wouldest not understand: although if I [had] sent thee to such, they would have hearkened to thee.
not to the many peoples of unfamiliar speech and difficult language whose words you cannot understand. Surely if I had sent you to them, they would have listened to you.
