Matthew Poole and continuators on Acts 28:4

4 And when the barbarians saw the venemous beast hang on his hand, they said among themselves. No doubt this man is a murderer, whom, though he hath escaped the sea, yet vengeance suffereth not to live.

So the Viper is called by that Appellative word; from whence also comes Theriaca, or Treacle, which is made out of flesh, or Trochusses of Vipers. And if men can make an Antidote out of Poyson, much more can God bring good out of evil.

It is a strange sense that men by the light of Nature had of Divine Vengeance; especially of Gods revenging of Murder. Hence they called one of their Furies, Tisiphone; as one that punished and revenged Murder. Yet they were to blame in this case, 1. Because they confine the punishment of wicked men wholly unto this Life. 2. In that they did not expect the event: They judged before they knew what would be the end of Paul afterwards. 3. They erred, in that they measured the goodness or badness of a man's state or cause by his prosperity or adversity.
