'Snakes' in the Bible

But when he saw a number of the Pharisees and Sadducees coming to his baptism, he said to them, Offspring of snakes, at whose word are you going in flight from the wrath to come?

See, I send you out as sheep among wolves. Be then as wise as snakes, and as gentle as doves.

You offspring of snakes, how are you, being evil, able to say good things? because out of the heart's store come the words of the mouth.

You snakes, offspring of snakes, how will you be kept from the punishment of hell?

They will take up snakes, and if there is poison in their drink, it will do them no evil; they will put their hands on those who are ill, and they will get well.

So he said to the people who went out to him for baptism: You offspring of snakes, at whose word are you going in flight from the wrath to come?

See, I have given you power to put your feet on snakes and evil beasts, and over all the strength of him who is against you: and nothing will do you damage.

Their throat is like an open place of death; with their tongues they have said what is not true: the poison of snakes is under their lips:

And let us not put the Lord to the test, as some of them did, and came to their death by snakes.

For the power of the horses is in their mouths and in their tails: because their tails are like snakes, and have heads, and with them they give wounds.
