In spite of all the excellent qualities of manna, they were not satisfied with it, and demanded that Moses and Aaron give them flesh to eat. These replied: "We might put up with you if you murmured only against us, but you murmur against the Eternal. Come forward, that you may hear the judgment of God." At once God appeared to Moses, and said to him: "It is revealed to Me what the congregation of Israel have said, and what they will say, but tell them this: You have demanded two things; you have desired bread, and I gave it to you, because man cannot exist without it; but now, filled to satiety, you demand flesh; this also will I give you, so that you might not say if your wish were denied. 'God cannot grant it,' but at some future time you shall make atonement for it; I am a judge and shall assign punishment for this." In the meantime, however, God granted their wish, and toward evening thick swarms of quails came up from the sea, and covered the whole camp, taking their flight quite low, not two ells above the ground, so that they might be easily caught. Contrary to the manna, which fell in the morning, the quails did not come before evenfall; with a radiant countenance God gave them the former, as their desire for bread was justified, but with a darkened mien, under cover of night, He sent quails. [116] Now, because the one food came in the morning and the second in the evening, Moses instituted the custom among his people of taking two meals a day, one in the morning and one in the evening; and he set the meal with the use of meat for the evening. [117] At the same time he taught them the prayer in which they were to offer thanks after eating manna, which read: "Blessed be Thou, O God our Lord, King of the world, who in Thy bounty, dost provide for all the world; who, in Thy grace, goodwill, and mercy, dost grant food to every creature, for Thy grace is everlasting. Thanks to Thy bounty we have never lacked food, nor ever shall lack it, for Thy great name's sake. For Thou suppliest and providest for all; Thou are bountiful, and nourishest all Thy creatures which Thou has made. Blessed be Thou, O God, that dost provide for all." [118] MIRIAM'S WELL
