How many people in the bible were persecuted for following Jesus?

Answer 1

Peter's death is foretold:

John 21

15 When they had finished breakfast, Jesus said to Simon Peter, "Simon, son of John, do you love me more than these?" He said to him, "Yes, Lord; you know that I love you." He said to him, "Feed my lambs." 16 He said to him a second time, "Simon, son of John, do you love me?" He said to him, "Yes, Lord; you know that I love you." He said to him, "Tend my sheep." 17 He said to him the third time, "Simon, son of John, do you love me?" Peter was grieved because he said to him the third time, "Do you love me?" and he said to him, "Lord, you know everything; you know that I love you." Jesus said to him, "Feed my sheep. 18 Truly, truly, I say to you, when you were young, you used to dress yourself and walk wherever you wanted, but when you are old, you will stretch out your hands, and another will dress you and carry you where you do not want to go." 19 (This he said to show by what kind of death he was to glorify God.) And after saying this he said to him, "Follow me."

Steven was stoned:

Acts 7

54 Now when they heard these things they were enraged, and they ground their teeth at him. 55 But he, full of the Holy Spirit, gazed into heaven and saw the glory of God, and Jesus standing at the right hand of God. 56 And he said, "Behold, I see the heavens opened, and the Son of Man standing at the right hand of God." 57 But they cried out with a loud voice and stopped their ears and rushed together at him. 58 Then they cast him out of the city and stoned him. And the witnesses laid down their garments at the feet of a young man named Saul. 59 And as they were stoning Stephen, he called out, "Lord Jesus, receive my spirit." 60 And falling to his knees he cried out with a loud voice, "Lord, do not hold this sin against them." And when he had said this, he fell asleep.

James was killed with a sword:

Acts 12

About that time Herod the king laid violent hands on some who belonged to the church. 2 He killed James the brother of John with the sword, 3 and when he saw that it pleased the Jews, he proceeded to arrest Peter also. This was during the days of Unleavened Bread. 4 And when he had seized him, he put him in prison, delivering him over to four squads of soldiers to guard him, intending after the Passover to bring him out to the people. 5 So Peter was kept in prison, but earnest prayer for him was made to God by the church.

John the baptist was beheaded:

Matthew 14

10 He sent and had John beheaded in the prison, 11 and his head was brought on a platter and given to the girl, and she brought it to her mother. 12 And his disciples came and took the body and buried it, and they went and told Jesus.

Additionally, there are extra-biblical sources that talk of the deaths of the early church figures:

Christianity was not decriminalized until February 313AD by the Edict of Milan, by emperor Constantine, so Christian persecution was the norm for most of its early history.
