'Serpents' in the Bible

“Behold, I send you out as sheep in the midst of wolves; so be shrewd as serpents and innocent as doves.

You serpents, you brood of vipers, how will you escape the sentence of hell?

they will pick up serpents, and if they drink any deadly poison, it will not hurt them; they will lay hands on the sick, and they will recover.”

Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing will injure you.

Nor let us try the Lord, as some of them did, and were destroyed by the serpents.

For the power of the horses is in their mouths and in their tails; for their tails are like serpents and have heads, and with them they do harm.
