Acts 9:23 - Ellicott's Commentary On The Whole Bible

After that many days were fulfilled. — We learn from the more definite statement in Galatians 1:18 that these few words cover a period of otherwise unrecorded work, extending over a period of three years. That period must have witnessed the growth of a Christian society at Damascus, with an order of discipline and worship based on the outlines of that at Jerusalem. It follows, however, from the subsequent history that, as yet, Gentile converts were not admitted to the Church as such. The special mission to them came later on (comp. Acts 22:21), and it was natural that one, with the intense affection for his brethren according to the flesh which characterised St. Paul (Romans 10:1), should, till that mission came, have given himself mainly, or even exclusively, to the work of labouring for their conversion. It is probable, however, from the bitter antagonism of the Jews, that his teaching had already pointed to the breaking down of “the middle wall of partition” (Ephesians 2:14), and the passing away of all on which they had prided themselves as being their exclusive privileges. From the first it might almost seem as if Stephen had risen from the dead, and was living again in the spirit and power of his persecutor.
