'Wilderness' in the Bible

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

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