Acts 6:8 through Acts 8:1a should all be one chapter for it tells the story of Stephen, one of the deacons selected earlier in chapter 6.
Stephen has been brought before the religious council, falsely accused by paid “witnesses”. Acts 7:2-53 is Stephen’s response to these accusations. He goes through a brief history of the Jewish people. If you read this in a Bible with good cross references you can go back and read in more detail the parts of this overall story.
When he accuses them of being like the disobedient people of the past they become enraged and kill him.
Acts 8:1 introduces Saul, later known as Paul.
