Ezekiel 36:24-26

For I will take you from among the nations, and gather you out of all the countries, and will bring you into your own land. And I will sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you. A new heart also will I give you, and a new spirit will I put within you; and I will take away the stony heart out of your flesh, and I will give you a heart of flesh.
