'Heart of Stone' in the Bible

And I have given to them one heart, And a new spirit I do give in your midst, And I have turned the heart of stone out of their flesh, And I have given to them a heart of flesh.

And I have given to you a new heart, And a new spirit I give in your midst, And I have turned aside the heart of stone out of your flesh, And I have given to you a heart of flesh.
