Nehemiah 9:19-21

even so, in the multitude of your mercies, you did not send them away in the desert. The pillar of cloud did not withdraw from them by day, so that it might lead them on the way, nor the pillar of fire by night, so that it might show them the way along which they might advance. And you gave them your good Spirit, so that he might teach them, and you did not withhold your manna from their mouth, and you gave them water in their thirst. For forty years, you fed them in the desert, and nothing was lacking to them; their garments did not grow old, and their feet were not worn down.
