Matthew Poole and continuators on Genesis 49:17

17 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.

Which covereth and hideth it self in the sand or dust of the high-way watching for men or beast that pass that way. He notes the subtilty of that Tribe, which should conquer their enemies more by craft and cunning than by strength or force of armes.
