he said to them, “Tell your master this: The Lord says, ‘Don’t be afraid of what you have heard. Don’t be frightened by the words the servants of the king of Assyria have spoken against me. Listen! I am going to put a spirit in the king of Assyria. He will hear a report that will make him return to his own country, and I will cause him to die by the sword there.'”
Isaiah 37:6-7 (NCV)
Those that belong to God have no reason to fear those that are against Him. Though enemies may make fun of and mock, they cannot hurt. God will ultimately judge.
