Scofield Reference Notes (1917 Edition)Chapter 6
6:1 And in those days, when the number of the disciples was multiplied, there arose a murmuring of the Grecians against the Hebrews, because their widows were neglected in the daily ministration.
6:5 And the saying pleased the whole multitude: and they chose Stephen, a man full of faith and of the Holy Ghost, and Philip, and Prochorus, and Nicanor, and Timon, and Parmenas, and Nicolas a proselyte of Antioch:
Hellenists, i.e. Grecian Jews.
6:15 And all that sat in the council, looking stedfastly on him, saw his face as it had been the face of an angel.
It is beautiful to see that these were all Hellenists, as the Grecian names show.
