Ezekiel 2:6; Ezekiel 3:9

6 "And you, son of man, neither fear them nor fear their words, though thistles and thorns are with you and you sit on scorpions; neither fear their words nor be dismayed at their presence, for they are a rebellious house.

9 "Like emery harder than flint I have made your forehead. Do not be afraid of them or be dismayed before them, though they are a rebellious house."
