Ezekiel 36:4, 26-27

therefore, O mountains of Israel, hear the word of the Lord GOD: Thus says the Lord GOD to the mountains and the hills, the ravines and the valleys, the desolate wastes and the deserted cities, which have become a prey and derision to the rest of the nations all around

And I will give you a new heart, and a new spirit I will put within you. And I will remove the heart of stone from your flesh and give you a heart of flesh. And I will put my Spirit within you, and cause you to walk in my statutes and be careful to obey my rules.
