Genesis 49:17

He will be a snake by the road, a viper in the path that bites the horse’s heels so that its rider tumbles backward.

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.

Note an adder: Heb. an arrow-snake

Dan will be a serpent on the trail, an adder in the path, that bites the horse’s heels, so that his rider falls backward.

Dan shall be a serpent in the way, An adder in the path, That biteth the horse’s heels, So that his rider falleth backward.
