"As he described the glorious scene upon which his eyes were gazing, it was more than his persecutors could endure. Stopping their ears, that they might not hear his words, and uttering loud cries, they ran furiously upon him with one accord “and cast him out of the city.” “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.” AA 101.1"
"And they stoned Stephen, calling upon God, and saying, Lord Jesus, receive my spirit."
The EGW passage directly quotes Acts 7:59.
"The martyrdom of Stephen made a deep impression upon all who witnessed it. The memory of the signet of God upon his face; his words, which touched the very souls of those who heard them, remained in the minds of the beholders, and testified to the truth of that which he had proclaimed. His death was a sore trial to the church, but it resulted in the conviction of Saul, who could not efface from his memory the faith and constancy of the martyr, and the glory that had rested on his countenance. AA 101.3"
"And all that sat in the council, looking stedfastly on him, saw his face as it had been the face of an angel."
Both passages refer to the appearance of Stephen's face, reflecting God's presence. EGW elaborates on the impression this made, which is thematically linked to the biblical account.
