“And they stirred up the people, and the elders, and the scribes, and came upon him, and caught him, and brought him to the council, And set up false witnesses, which said, This man ceaseth not to speak blasphemous words against this holy place, and the law:” - Acts 6:12, 13.
While St. Stephen was making his famous oration in defence of the faith, there stood against him certain of the synagogue of the Libertines, and Cyrenians and Alexandrians, of Cilicia and of Asia, who found to their dismay that that they could not withstand his arguments. However, when they found they “were not able to resist the wisdom and the spirit by which he spake” they hired men who said they heard Stephen “speak blasphemous words against Moses, and against God,” stirring up the elders and the people. (Acts 6:9-15) That Stephen announced that he saw a vision was only the last straw they needed to stone him to death. The danger of involving oneself in ungodliness is that even after one had repented and had been forgiven the record (at least with men) still remains and stays somewhere in the inner recesses of people's memory. We should strive to avoid sin at all costs. – Job 28:28.
