'Hills' in the Bible

Art thou the first man that was born? or wast thou made before the hills?

From the inundation of hills they are wet, And without a refuge -- have embraced a rock.

The earth is changed as clay is by a seal;its hills stand out like the folds of a garment.

It ranges the hills as its pasture, and searches after every green plant.

The hills yield food for him,while all sorts of wild animals play there.
