Dan will be a serpent in the way, an adder in the path, That bites the horse's heels, so that his rider falls backward.

Don't rejoice, O Philistia, all of you, because the rod that struck you is broken; for out of the serpent's root an adder will emerge, and his fruit will be a fiery flying serpent.

They hatch adders' eggs, and weave the spider's web: he who eats of their eggs dies; and that which is crushed breaks out into a viper.

For, behold, I will send serpents, adders, among you, which will not be charmed; and they shall bite you, says Yahweh.
