Exodus 9:12  (King James Version)
And the LORD hardened the heart of Pharaoh, and he hearkened not unto them; as the LORD had spoken unto Moses.

4:21 Exodus 7:13 Exodus 7:14 Psalms 81:11 Psalms 81:12 ; Revelation 16:10 Revelation 16:11
Hardness of heart is a figurative expression, denoting that insensibility of mind upon which neither judgments nor mercies make any abiding impressions; but the conscience being stupefied, the obdurate rebel persists in determined disobedience.
