Nehemiah 9:19-21

19“Because of your great compassion you did not abandon them in the wilderness. By day the pillar of cloud did not fail to guide them on their path, nor the pillar of fire by night to shine on the way they were to take. 20You gave your good Spirit to instruct them. You did not withhold your manna from their mouths, and you gave them water for their thirst. 21For forty years you sustained them in the wilderness; they lacked nothing, their clothes did not wear out nor did their feet become swollen.
