It was in the barren wilderness that Israel learned to trust God for supernatural provision. Whether it was the initial wilderness journey preparing them to enter the promised land, or the forty year trek experienced as chastisement for their rebellion--God
provided for them.
The Word records that their clothes did not wear out, nor did their feet outgrow their shoes during all those years (Deuteronomy 8:4). God prepared a table for them in the wilderness (Psalm 78:19), providing both water and manna for food (Exodus 16:32).
