Ezekiel 3:2-6

So I opened my mouth, and he caused me to eat that roll.

And he said unto me, Son of man, cause thy belly to eat, and fill thy bowels with this roll that I give thee. Then did I eat it; and it was in my mouth as honey for sweetness.

And he said unto me, Son of man, go, get thee unto the house of Israel, and speak with my words unto them.

For thou art not sent to a people of a strange speech and of an hard language, but to the house of Israel;

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.
