'Wounding' in the Bible

Death will overtake great as well as small in the land: their bodies will not be put in a resting-place, and no one will be weeping for them or wounding themselves or cutting off their hair for them:

The hair is cut off from the head of Gaza; Ashkelon has come to nothing; the last of the Anakim are deeply wounding themselves.

Make sounds of grief, O Heshbon, for Ai is wasted; give loud cries, O daughters of Rabbah, and put haircloth round you: give yourselves to weeping, running here and there and wounding yourselves; for Milcom will be taken prisoner together with his rulers and his priests.
