Yea, they made their hearts as an adamant stone, lest they should hear the law, and the words which the Lord of hosts hath sent in his spirit by the former prophets.

Zechariah 7:12

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 an heart of flesh.  And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.

Ezekiel 36:26‭-‬27
