Stephen

one of the seven deacons, who became a preacher of the gospel.
He was the first Christian martyr. His personal character and
history are recorded in Acts 6. "He fell asleep" with a prayer
for his persecutors on his lips (7:60). Devout men carried him
to his grave (8:2).

It was at the feet of the young Pharisee, Saul of Tarsus, that
those who stoned him laid their clothes (compare Deut. 17:5-7)
before they began their cruel work. The scene which Saul then
witnessed and the words he heard appear to have made a deep and
lasting impression on his mind (Acts 22:19, 20).

The speech of Stephen before the Jewish ruler is the first
apology for the universalism of the gospel as a message to the
Gentiles as well as the Jews. It is the longest speech contained
in the Acts, a place of prominence being given to it as a
defence.
