14 Oct Acts 7:53-54

53 “…you who received the law as ordained by angels, and yet did not keep it”. Now when they heard this, they were cut to the quick, and they began gnashing their teeth at him.

Stephen, with the power of the Holy Spirit, spoke the truth. He spoke of Abraham, Joseph, Moses, and David. He spoke of the prophets that had been killed, and he spoke of the prophecies pointing to Jesus as the Messiah. The council had two options; they could listen and understand, accepting the truth, OR they could reject the truth and get angry. The Bible tells us these men, the Sanhedrin, who were experts in the Old Testament were cut to the quick. That means they knew Stephen was right and they were wrong, and they chose anger.
