Revelation 11.8
Note 11.8 The Great City. The city of Jerusalem which crucified the Lord Jesus and took the lives of numerous early Christians.(Acts 5.28-30; 7.58-60; 12.2; 26.10)
These are the referenced passages of Acts : not only was Jesus killed by the city of Jerusalem but Jerusalem also martyred the Catholic saints and persecuted the Church.
Acts 5
27 When they had brought them, they had them stand before the council. The high priest questioned them, 28saying, ‘We gave you strict orders not to teach in this name,* yet here you have filled Jerusalem with your teaching and you are determined to bring this man’s blood on us.’ 29But Peter and the apostles answered, ‘We must obey God rather than any human authority.* 30The God of our ancestors raised up Jesus, whom you had killed by hanging him on a tree.
Acts 7
56‘Look,’ he said, ‘I see the heavens opened and the Son of Man standing at the right hand of God!’ 57But they covered their ears, and with a loud shout all rushed together against him. 58Then they dragged him out of the city and began to stone him; and the witnesses laid their coats at the feet of a young man named Saul. 59While they were stoning Stephen, he prayed, ‘Lord Jesus, receive my spirit.’ 60Then he knelt down and cried out in a loud voice, ‘Lord, do not hold this sin against them.’ When he had said this, he died
Acts 12
About that time King Herod laid violent hands upon some who belonged to the church. 2He had James, the brother of John, killed with the sword. 3After he saw that it pleased the Jews, he proceeded to arrest Peter also. (This was during the festival of Unleavened Bread.) 4When he had seized him, he put him in prison and handed him over to four squads of soldiers to guard him, intending to bring him out to the people after the Passover. 5While Peter was kept in prison, the church prayed fervently to God for him.
Acts 26
9 ‘Indeed, I myself was convinced that I ought to do many things against the name of Jesus of Nazareth.* 10And that is what I did in Jerusalem; with authority received from the chief priests, I not only locked up many of the saints in prison, but I also cast my vote against them when they were being condemned to death. 11By punishing them often in all the synagogues I tried to force them to blaspheme; and since I was so furiously enraged at them, I pursued them even to foreign cities.
