'Dry' in the Bible

“Will You cause a windblown leaf to tremble?Will You pursue the chaff of the dry stubble?

“He will not escape from darkness [fleeing disaster];The flame [of God’s wrath] will wither his branch,And by the blast of His mouth he will go away.

“They are gaunt with want and famine;They gnaw the dry and barren ground by night in [the gloom of] waste and desolation.
