1 Peter 3:13 - Matthew Poole's English Annotations on the Holy Bible

And who is he that will harm you? i.e. none or few will harm you, as being convinced and overcome by your good deeds, whereby even they are many times mollified and melted that are of themselves most wicked and hard-hearted, 1 Samuel 24:16,17. If ye be followers of that which is good; either followers of God, who doth good to the evil and unkind; but then it should be rendered, followers of him who is good, or rather, followers of those things that are good: q.d. If you be diligent in doing good to others, none will have the heart to do you hurt.
