Matthew Poole and continuators on Acts 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.

These were not such, as are elsewhere called Greeks, either as being of that Nation, or more generally taken for all Gentiles at large; but they were (as to their Authority) Iews, and descended from such of them, who in several national calamities, were forced (or chose) to leave their Countrey, and fly to Alexandria, and divers other places; yet kept themselves unmixed with other Nations, retaining the knowledge of God▪ and coming to worship upon the solem Feasts; onely disusing the Hebrew Language, they were more acquainted with the Greek Tongue, (then, commonly) spoken every where) and used the holy Scripture Translated into that Language, which made them the rather called Hellenists or Grecians.

They were not taken, as others, into the Colledge, or number of widows, who in that time had some care of the poor; or rather, because they were not so largely allowed, or carefully looked after; for those that sold their goods, being Hebrews, they might not be so tender over the Hellenists, whose estates laying farther off, could not so readily be sold for the relief of themselves or others.
