Yechezkel 3:4-6

Orthodox Jewish Bible

⁴ And He said unto me, Ben Adam, go, get thee unto the Bais Yisroel, and speak My words unto them.

⁵ For thou art not sent to an Am Imkei Safah (a people of indecipherable language) and of obscure lashon, but to Bais Yisroel;

⁶ Not to amim rabbim of indecipherable language and obscure lashon whose words thou canst not understand. Surely, had I sent thee to them, they would have paid heed unto thee.
