'In the Wilderness' in the Bible

Yet you in your manifold mercies forsook them not in the wilderness: the pillar of cloud departed not from them by day, to lead them in the way; neither the pillar of fire by night, to show them light, and the way in which they should go.

Yea, forty years did you sustain them in the wilderness, so that they lacked nothing; their clothes grew not old, and their feet swelled not.
