'Snake' in the Bible

Or if he asks for a fish, he wouldn't give him a snake, would he?

What father among you, if his son asks for bread, would give him a stone, or if he asks for a fish, would give him a snake instead of the fish?

Paul gathered a bundle of sticks and put it on the fire. A poisonous snake was forced out by the heat and attached itself to Paul's hand.

When the people who lived there saw the snake hanging from his hand, they told one another, "This man must be a murderer! He may have escaped from the sea, but Justice won't let him live."

But he shook the snake into the fire and wasn't harmed.
