"Neither shall ye use enchantments" ... (Lev. xix. 26). Such, for instance, as those practiced with cats, fowls, and fishes.
Sanhedrin, fol. 66, col. 1.
Rav Ketina happened once, in his travels, to hear the noise of an earthquake just as he came opposite to the abode of one who was wont to conjure with human bones. Happening to mutter aloud to himself as he passed, "Does the conjurer really know what that noise is?" a voice answered, "Ketina, Ketina, why shouldn't I know? When the Holy One—blessed be He!—thinks of His children who dwell in sorrowful circumstances among the nations of the earth, He lets fall two tears into the great sea, and His voice is heard from one end of the world to the other, and that is the rumbling noise we hear." Upon which Rav Ketina protested, "The conjurer is a liar, his words are not true; they might have been true, had there been two rumbling noises." The fact was, two such noises were heard, but Rav Ketina would not acknowledge it, lest, by so doing, he should increase the popularity of the conjurer. Rav Ketina is of the opinion that the rumbling noise is caused by God clapping His hands together, as it is said (Ezek. xxi, 22; A.V., ver. 17), "I will also smite My hands together, and I will cause My fury to rest."
Berachoth, fol. 59, col. 1.
Rabbi Elazar ben Azariah proclaimed this anathema with the blast of three hundred trumpets:—"Whoever shall take drink from the hand of a bride, no matter whether she be the daughter of a disciple of the wise or the daughter of an Amhaaretz, it is all one as if he drunk it from the hand of a harlot." Again, it is said, "He who receives a cup from the hands of a bride and drinks it therefrom, has no portion whatever in the world to come."
Tract Calah.
There was a place for collecting the ashes in the middle of the altar, and there were at times in it nearly as much as three hundred cors (equal to about 2830 bushels) of ashes. On Rava remarking that this must be an exaggeration, Rav Ammi said the law, the prophets, and the sages are wont to use hyperbolical language. Thus the law speaks of "Cities great and walled up to heaven" (Deut. i. 28); the prophets speak of "the earth rent with the sound of them" (1 Kings i. 40); the sages speak as above and also as follows. There was a golden vine at the entrance of the Temple, trailing on crystals, on which devotees who could used to suspend offerings of fruit and grape clusters. "It happened once," said Rabbi Elazer ben Rabbi Zadoc, "that three hundred priests were counted off to clear the vine of the offerings."
Chullin, fol. 90, col. 2.
Three hundred priests were told off to draw the veil (of the Temple) aside; for it is taught that Rabbi Shimon ben Gamliel declared in the name of Rabbi Shimon the Sagan (or high priest's substitute), that the thickness of the veil was a handbreadth. It was woven of seventy-two cords, and each cord consisted of twenty-four strands. It was forty cubits long and twenty wide. Eighty-two myriads of damsels worked at it, and two such veils were made every year. When it became soiled, it took three hundred priests to immerse and cleanse it.
