A.T. Robertson Commentary Acts 26:4

"My manner of life then from my youth up, which was from the beginning among mine own nation and at Jerusalem, know all the Jews;" — Acts 26:4 (ASV)

My manner of life (την μεν ουν βιωσιν μου). With μεν ουν Paul passes from the capt-

atio benevolentiae (verses 1,2) "to the narratio or statement of his case" (Page). Βιωσις is from βιοω (1 Peter 4:2) and that from βιος (course of life). This is the only instance of βιωσις yet found except the Prologue (10) of Ecclesiasticus and an inscription given in Ramsay's Cities and Bishoprics of Phrygia, Vol II, p. 650.

Know (ισασ). Literary form instead of the vernacular Koine οιδασιν. Paul's early life in Tarsus and Jerusalem was an open book to all Jews.
