The New Testament speaks of Stephen, who was chosen by the apostles to aid with the labor of the early church. The book of Acts describes Stephen as a man full of faith and power who did wonders and miracles among the people. So much so, that they were unable to resist the wisdom and spirit with which he spoke. The leaders of the council set up false witnesses to speak in opposition to Stephen saying he had spoken blasphemous words and they created the circumstances for him to be stoned. As is described concerning Jesus while dying on the cross, despite the fact that he was dying, Stephen prayed for his assailants. Note it states he fell asleep. This indicates a peaceful death even while being stoned.
“And they stoned Stephen, calling upon God, and saying, Lord Jesus, receive my spirit. 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.” (Acts 7:59-60)
