ליטעראַטור פֿון בית שני אויף בראשית 4:13

This number of a hundred and sixty-five is combined of the singular addition of ten numbers from the unit to ten; as one, two, three, four, five, six, seven, eight, nine, ten, the total of which is fiftyfive. And again, from that by the addition of ten numbers, which, removing the unit proceed upwards by twos, and two, four, six, eight, ten, twelve, fourteen, sixteen, eighteen, twenty, which make a hundred and ten; the combination of which, with the numbers first mentioned, produces a hundred and sixty-five; and in this addition the even numbers amount to twice as much as the odd numbers; for the woman is more violent than the man, in the preposterous manner in which the wicked man rules over the virtuous man, the outward sense over the mind, the body over the outward sense, and matter over its cause. But the number two hundred, in which repentance was practised, is combined of two numbers of one hundred, the first hundred of which intimates a purification from injustice, but the other indicates the plenitude of perfect virtue. In truth, before anything else is done, the first thing is to cut off from a sick body every diseased part, and after that means of cure are to be applied to it, for this is the first step, and the other the second. Moreover, the number two hundred consists of fours, for it is produced as from seed, from four triangular numbers, and from four tetragons, and from four pentagons, and from four hexagons, and from four heptagons; and, as one may say, it fixes its step on the number seven. Now the four triangles are these, one, three, six, ten, which make twenty; the four tetragons are one, four, nine, sixteen, which make thirty; from the four pentagons, one, five, twelve, twenty-two, is made the number forty. Moreover, the four hexagons, one, six, fifteen, twenty-eight, make fifty; and the four heptagons, one, seven, eighteen, thirty-four, make sixty; and all these numbers put together make two hundred.

[165] One of the foolish who saw to what a pitch of misery free licence to sin leads said boldly, “That I should be let free is the greater indictment” (Gen. 4:13). For it is a terrible thing that the soul, so wild as it is by nature, should be suffered to go unbridled, when even under the rein and with the whip in full play it can hardly be controlled and made docile.
