Romans 5:12

As by one man...in whom [2] all have sinned. That is, in which man all sinned, (not in which death all sinned) as it must be the construction by the Greek text: so that these words are a clear proof of original sin against the Pelagian heretics, as St. Augustine often brings them. Nor does St. John Chrysostom deny original sin, though in this place he expounds it that all by Adam's sin were made guilty of death and punishments. But how could they deserve these, had they not sinned in Adam? (Witham)

In quo omnes peccaverunt, Greek: eph o pantes emarton. If it agreed with sin, in the Greek it must have been Greek: eph es.
