'Serpents' in the Bible

"Behold, I send you out as sheep in the midst of wolves. Therefore be wise as serpents, and harmless as doves.

You serpents, you offspring of vipers, how will you escape the judgment of Gehenna?

they will take up serpents; and if they drink any deadly thing, it will in no way hurt them; they will lay hands on the sick, and they will recover."

Behold, I give you authority to tread on serpents and scorpions, and over all the power of the enemy. Nothing will in any way hurt you.

Neither let us test the Lord, as some of them tested, and perished 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 harm.
