and twelve is the perfect number, of which the circle of the zodiac in the heaven is a witness, studded as it is with such numbers of brilliant constellations. The periodical revolution of the sun is another witness, for he accomplishes his circle in twelve months, and men also reckon the hours of the day and of the night as equal in number to the months of the year,

and the passages are not few in which Moses celebrates this number, describing the twelve tribes of his nation, appointing by law the offering of the twelve cakes of shewbread, and ordering twelve stones, on which inscriptions are engraved, to be woven into the sacred robe of the garment, reaching down to the feet of the high-priest, on his oracular dress.

He also celebrates the number seven, multiplied by the number ten; at one time speaking of the seventy palm-trees by the fountains, and in other passages he speaks of the elders, who were only seventy in number, to whom the divine and prophetical Spirit was vouchsafed. And again, it is the same number of heifers which are sacrificed at the solemn festival of the feast of tabernacles, [*] in a regular and proper division and order, for they are not all sacrificed together, but in seven days, the beginning being made with thirteen bulls; for thus, by every day subtracting one till they come to the number seven, the arranged number of seventy is properly completed.
