Ezekiel 3:6
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
Not to many people of a strange speech and of an hard language (note: Heb. deep of lip, and heavy language), whose words thou canst not understand. Surely, had I sent thee to them, they would have hearkened unto 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.
