'Heels' in the Bible

Dan will be a serpent on the way, A horned snake on the path, Which biteth the horse's heels, So that the rider falleth backwards.

And Barak summoned Zeb'ulun and Naph'tali to Kedesh; and ten thousand men went up at his heels; and Deb'orah went up with him.

the princes of Is'sachar came with Deb'orah, and Is'sachar faithful to Barak; into the valley they rushed forth at his heels. Among the clans of Reuben there were great searchings of heart.

And if thou say in thy heart, Wherefore come these things upon me? For the greatness of thine iniquity are thy skirts uncovered, and thy heels have suffered violence.
