'Stroke' in the Bible

Woe is me, for my wound! My stroke is hard to heal, and I had said, Yea, this is my grief, and I will bear it.

All thy lovers have forgotten thee; they seek thee not. For I have smitten thee with the stroke of an enemy, with the chastisement of a cruel one, for the greatness of thine iniquity: thy sins are manifold.
