Matthew Poole and continuators on Acts 8:3

3 As for Saul , he made havock of the church, entring into every house, and haling men and women , committed them to prison.

Saul was a degree beyond the ordinary sort of persecutors, and was, as he does acknowledge of himself, eminently injurious, 1 Tim. 1.13.

House after house, sparing none.

As by the hair of their heads.

This to be sure, the Iews had yet retained power from the Romans to do: All this is but as a foil, to illustrate more the riches of Gods mercy towards Saul.
