acts 28:3 And when Paul had gathered a bundle of sticks, and laid them on the fire, there came a viper out of the heat, and fastened on his hand. - Free Bible Online

      3. when Paul had gathered a bundle of sticks--"a quantity of dry sticks." The vigorous activity of Paul's character is observable in this comparatively trifling action [WEBSTER and WILKINSON].
      and laid them on the fire, there came a viper out of the heat--Having laid itself up among the sticks on the approach of the cold winter season, it had suddenly recovered from its torpor by the heat.
      and fastened--its fangs.
      on his hand--Vipers dart at their enemies sometimes several feet at a bound. They have now disappeared from Malta, owing to the change which cultivation has produced.
