Do not be in dread, you people, and do not become stupefied. Have I not from that time on caused you individually to hear and told it out? And you are my witnesses. Does there exist a God besides me? No, there is no Rock. I have recognized none.’”​—Isaiah 44:6-8.

His people need not fear to bear witness to this truth, since they have the support of Jehovah, who is as firm and stable as a massive rock!​—Deuteronomy 32:4; 2 Samuel 22:31, 32.
