He made havoc of the church; Saul was a degree beyond the ordinary sort of persecutors, and was, as he does acknowledge himself, eminently injurious, 1 Timothy 1:13. Entering into every house; house after house, sparing none. Haling men and women; as by the hair of their heads. Committed them to prison; this to be sure the Jews had yet retained power from the Romans to do. All this is but as a foil, to illustrate more the riches of God's mercy towards Saul.
