John Gill Commentary Acts 8:3

"But Saul laid waste the church, entering into every house, and dragging men and women committed them to prison." — Acts 8:3 (ASV)

As for Saul, he made havoc of the church
Did evil to the saints, destroyed them that called upon the name of Christ, (Acts 9:13Acts 9:21) and persecuted and wasted the church of God, as he himself says, (1:13) and now did Benjamin, of which tribe Saul was, ravine as a wolf, (Genesis 49:27)

Entering into every house ;
where the saints dwelt:

and haling men and women :
in a violent manner, without any regard to age or sex:

committed them to prison ;
delivered them up into the hands of the chief priests and magistrates, in order to be committed and sent to prison; this he himself confesses, (Acts 22:4) (26:10) .
