And you, son of man, be not afraid of them, neither be afraid of their words; though briers and thorns are all around you and you dwell and sit among scorpions, be not afraid of their words nor be dismayed at their looks, for they are a rebellious house. And you shall speak My words to them whether they will hear or refuse to hear, for they are most rebellious.

Ezekiel 2:6-7 (AMP)

Do not be afraid to speak the truth, or be put off by the words of those that would hinder you. In uncompromising service to God, speak and act boldly with assured protection from above.
