על חיי משה, ספר א ל״וOn the Life of Moses, Book I 36

א׳
1[196] Moses, when reviled in this way, was indignant not so much at their denunciations of himself as at their instability of judgement. For, after experiencing strange events outside the customary without number, they should have ceased to be guided by anything that is specious and plausible, but should have put their trust in him of whose unfailing truthfulness they had received the clearest proofs.
ב׳
2[197] But, on the other hand, when he considered the want of food, as great a misfortune as any that can befall mankind, he forgave them, knowing that the multitude by its very nature is an unstable thing, shaken by the circumstances of the moment, which produce oblivion of the past and despondency of the future. So, while they were all thus overwhelmed by affliction,
ג׳
3[198] and expecting the extreme misfortunes which they believed to be close at hand, ready to attack them, God, moved partly by the clemency and benevolence to man which belongs to His nature, partly too by His wish to honour the ruler whom He had appointed, and still more to bring home to them the greatness of that ruler’s piety and holiness as shewn in matters both clear and obscure, took pity on them and healed their sufferings.
ד׳
4[199] He, therefore, devised new and strange forms of benefaction, that by clearer manifestations they might now be schooled not to shew bitter resentment if something did not at once turn out as they would have it, but bear it patiently in expectation of good to come.
ה׳
5[200] What, then, did happen? On the morrow about daybreak, a great quantity of dew lay deep around the whole camp, showered noiselessly by God; a strange, extraordinary rain, not water, nor hail, nor snow, nor ice, such as are produced by the changes in the clouds at the winter solstice, but of grains exceedingly small and white, which, poured down in a continuous flow, lay in heaps in front of the tents. It was an incredible sight; and, in astonishment thereat, they asked their leader, “What is this rain, which no man ever saw before, and for what purpose has it come?”
ו׳
6[201] Moses, in answer, possessed by divine inspiration, spoke these oracular words: “Mortals have the deep-soiled plainland given over to them, which they cut into furrows with the plough, and there sow their seed, and perform the other tasks of the husbandman, thus providing the yearly fruits, and through them abundance of the necessaries of life. But God has subject to Him not one portion of the universe, but the whole world and its parts, to minister as slaves to their master for every service that He wills.
ז׳
7[202] So now it has seemed good to Him that the air should bring food instead of water, for the earth too often brings rain. What is the river of Egypt, when every year it overflows and waters the fields with its inroads, but a rainpour from beneath?”
ח׳
8[203] This work of God was strange enough even if it had stopped at this point, but actually there were other facts still stronger enhancing its marvels. For the men brought vessels from every quarter, and collected the grains, some on their beasts, others in burdens on their shoulders, thinking thus to store up provisions to last for later use.
ט׳
9[204] But, as it turned out, it was impossible to store or hoard them, since it was God’s purpose to bestow gifts ever new. For when they took a sufficient stock for their needs at the time, they consumed it with pleasure, but anything they left for the morrow they found did not keep, but changed and stank and was full of such life as is regularly bred in putrescence. This they naturally threw away, but found other food prepared for them, rained upon them with the dew every day.
י׳
10[205] A special distinction was given to the sacred seventh day,  for, since it was not permitted to do anything on that day, abstinence from works great or small being expressly enjoined, and therefore they could not then gather what was necessary, God rained a double supply the day before, and bade them bring in what would be sufficient for two days. And what was thus collected kept sound, nor did any of it decay at all as in the previous case.
