Genesis 49:15-17

King James Version

¹⁵ And he saw that rest was good, and the land that it was pleasant; and bowed his shoulder to bear, and became a servant unto tribute.

¹⁶ Dan shall judge his people, as one of the tribes of Israel.

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.
