Nor is this world inhabited by man the first of things earthly created by God. He made several worlds before ours, but He destroyed them all, because He was pleased with none until He created ours.[5] But even this last world would have had no permanence, if God had executed His original plan of ruling it according to the principle of strict justice. It was only when He saw that justice by itself would undermine the world that He associated mercy with justice, and made them to rule jointly.[6] Thus, from the beginning of all things prevailed Divine goodness, without which nothing could have continued to exist. If not for it, the myriads of evil spirits had soon put an end to the generations of men. But the goodness of God has ordained, that in every Nisan, at the time of the spring equinox, the seraphim shall approach the world of spirits, and intimidate them so that they fear to do harm to men. Again, if God in His goodness had not given protection to the weak, the tame animals would have been extirpated long ago by the wild animals. In Tammuz, at the time of the summer solstice, when the strength of behemot is at its height, he roars so loud that all the animals hear it, and for a whole year they are affrighted and timid, and their acts become less ferocious than their nature is. Again, in Tishri, at the time of the autumnal equinox, the great bird ziz[7] flaps his wings and utters his cry, so that the birds of prey, the eagles and the vultures, blench, and they fear to swoop down upon the others and annihilate them in their greed. And, again, were it not for the goodness of God, the vast number of big fish had quickly put an end to the little ones. But at the time of the winter solstice, in the month of Tebet, the sea grows restless, for then leviathan spouts up water, and the big fish become uneasy. They restrain their appetite, and the little ones escape their rapacity. Finally, the goodness of God manifests itself in the preservation of His people Israel. It could not have survived the enmity of the Gentiles, if God had not appointed protectors for it, the archangels Michael and Gabriel.[8] Whenever Israel disobeys God, and is accused of misdemeanors by the angels of the other nations, he is defended by his designated guardians, with such good result that the other angels conceive fear of them. Once the angels of the other nations are terrified, the nations themselves venture not to carry out their wicked designs against Israel. That the goodness of God may rule on earth as in heaven, the Angels of Destruction are assigned a place at the far end of the heavens, from which they may never stir, while the Angels of Mercy encircle the Throne of God, at His behest.[9] THE ALPHABET
