'Stony' in the Bible

When their judges are overthrown in stony places, they shall hear my words; for they are sweet.

“For he will be like a bush in the desertAnd will not see when prosperity comes,But will live in stony wastes in the wilderness,A land of salt without inhabitant.

And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them an heart of flesh:

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.
