There is poison in the fang of the serpent, in the mouth of the fly and in the sting of a scorpion; but the wicked man is saturated with it.

The serpent may, without being poisonous, raise high its hood, but the show of terror is enough to frighten people -- whether he be venomous or not.

Of a rascal and a serpent, the serpent is the better of the two, for he strikes only at the time he is destined to kill, while the former at every step.

What! Wouldst thou have a serpent sting thee twice?

Their poison is like the poison of a serpent: they are like the deaf adder that stoppeth her ear; / Which will not hearken to the voice of charmers, charming never so wisely.

They have sharpened their tongues like a serpent; adders' poison is under their lips. Selah.
