'Wilderness' in the Bible

yet thou in thy manifold mercies forsookest them not in the wilderness: the pillar of cloud departed not from over them by day, to lead them in the way; neither the pillar of fire by night, to show them light, and the way wherein they should go.

Yea, forty years didst thou sustain them in the wilderness, and they lacked nothing; their clothes waxed not old, and their feet swelled not.
