'Hardening' in the Bible

Even now I'm hardening the heart of the Egyptians so they'll go after the Israelis. Then I'll receive honor by means of Pharaoh and all his army, his chariots, and his horsemen.

In the hardening of dust into hardness, And clods cleave together?

O the happiness of a man fearing continually, And whoso is hardening his heart falleth into evil.

A man often reproved, hardening the neck, Is suddenly broken, and there is no healing.
