Chapter XI.—Precepts of Elchasai. But in very many other respects he talks folly, inculcating the use of these sentences also for those afflicted with consumption, and that they should be dipped in cold water forty times during seven days; and he prescribes similar treatment for those possessed of devils. Oh inimitable wisdom and incantations gorged with powers! 1022 Who will not be astonished at such and such force of words? But since we have stated that they also bring into requisition astrological deceit, we shall prove this from their own formularies; for Elchasai speaks thus:  “There exist wicked stars of impiety. This declaration has been now made by us, O ye pious ones and disciples:  beware of the power of the days of the sovereignty of these stars , and engage not in the commencement of any undertaking during the ruling days of these. And baptize not man or woman during the days of the power of these stars , when the moon, (emerging) from among them, courses the sky , and travels along with them. Beware of the very day up to that on which the moon passes out from these stars , and then baptize and enter on every beginning of your works. But, moreover, honour the day of the Sabbath, since that day is one of those during which prevails (the power) of these stars . Take care, however, not to commence your works the third day from a Sabbath, since when three years of the reign of the emperor Trojan are again completed from the time that he subjected the Parthians to his own sway,—when, I say , three years have been completed, war rages between the impious angels of the northern constellations; and on this account all kingdoms of impiety are in a state of confusion.” 1022     Miller suggests the singular number ( δυνάμεως ).
