Ezekiel 2:4, 6

For they are impudent children and stiffhearted. I do send thee unto them; and thou shalt say unto them, Thus saith the Lord GOD.

And thou, son of man, be not afraid of them, neither be afraid of their words, though briers and thorns be with thee, and thou dost dwell among scorpions: be not afraid of their words, nor be dismayed at their looks, though they be a rebellious house.
