Adder

Dan shall be a serpent by the way, an adder in the path, that biteth the horse heels, so that his rider shall fall backward.

Their poison is like the poison of a serpent: they are like the deaf adder that stoppeth her ear;

Thou shalt tread upon the lion and adder: the young lion and the dragon shalt thou trample under feet.

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

At the last it biteth like a serpent, and stingeth like an adder.
