Yechezkel 2:2-3

And the Ruach entered into me just as He spoke unto me, and stood me upon my raglayim, that I heard Him that spoke unto me. And He said unto me, Ben Adam, I send thee to the Bnei Yisroel, to Goyim HaMoredim (Rebellious Nations) that hath rebelled against Me; they and their Avot have rebelled against Me, even unto this very day.
