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

He shall suck the serpent's gall, and the adder's tongue shall slay him:

They are as venomous as the poison of a serpent, even like the deaf adder that stoppeth her ears,

Thou shalt go upon the Lion and Adder, the young Lion and the Dragon shalt thou tread under thy feet.

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

It goeth down softly; but at the last it biteth like a serpent, and stingeth as an adder.

Rejoice not, thou whole Philistia, as though the rod of him that beateth thee were broken: For out of the serpent's root, there shall come an adder, and the fruit shall be a fiery worm.
