This is from Acts 6 and 7. It shows the mock trial of Stephen, and the glorious spiritual manifestations, but the people's hearts were too hardened to even notice. Paul watches the coats:
54 ¶When they heard these things, they were cut to the heart, and they gnashed on him with their teeth.
55 But he, being full of the Holy Ghost, looked up steadfastly into heaven, and saw the glory of God, and Jesus standing on the right hand of God,
56 And said, Behold, I see the heavens opened, and the Son of man standing on the right hand of God.
58 And cast him out of the city, and stoned him: and the witnesses laid down their clothes at a young man’s feet, whose name was Saul.
60 And he kneeled down, and cried with a loud voice, Lord, lay not this sin to their charge. And when he had said this, he fell asleep.
