'Wilderness' in the Bible

And beyond the Jordan [at] Jericho, on the east side of the Jordan, out of the tribe of Reuben: Bezer in the wilderness with its pasturelands, Jahzah with its pasturelands,

And from the Gadites, valiant mighty warriors, {soldiers fit for war}, expert with shield and spear, defected to David at the fortress toward the wilderness. And {they had faces like lions} [and were] swift as gazelles upon the mountains.
