In the ninth place, it is divided into forty and sixty, each of which is a very natural number; and in accordance with the first order of decimals up to ten thousand in a quinquangular figure the number a hundred holds the middle place; for instance: one, ten, a hundred, one thousand, ten thousand, where a hundred is the middle number of one, ten, a hundred, one thousand, and ten thousand.

But we ought also not to pass over in silence the number ninety as far as it concerns the visible characters. As it seems to me the number ninety is second only to the number a hundred, inasmuch as the tenth part of it, that is to say ten, is taken away, since I see that in the law two-tenths of the firstfruits were set apart, first a tenth of the whole, secondly a tenth of the remainder, for when a tenth of the fruits of the earth, of corn, or wine, or oil, is taken, another tenth is also taken from the remainder; therefore of these two that which is the first and principal one is honoured with the greater share; and in the second place that which follows it, since the number a hundred of the years of the wise man comprises both the first-fruits with which it is consecrated, both the first and the second kind; but the number ninety of the years of the female parent, comprehends the second and lesser first-fruits, namely, the remainder of the first, which is the great one among the sacred numbers. This therefore may be called the first vision in the sacred law which is familiar; and the other has a general character, for the number ninety is fertile; on which account also it happens that the woman begins to bring forth in the ninth month; but the tenth is the sacred and perfect number; and when the two numbers nine and ten are multiplied together ninety is made, as being the virtue of the sacred birth, receiving a fertile generation according to the number nine, and a holy one according to ten.
