Philo Judaeus De Posteritate Caini 173

[173] On this account Abel, after having quitted the mortal body, ^{1 2 3} departed to the better nature, and took up his abode with that. But Seth, as being the seed of human virtue, will never quit the race of mankind. But first of all he will receive his growth up to the number ten, that perfect number, according to which the just Noah exists; and then he will receive a second and a better growth from his son Shem, ending in a second ten, from which the faithful Abraham is named. And he will also have a third growth, and one more perfect than the number ten, extending from him to Moses, that man who is wise in all things, for he is the seventh from Abraham, not revolving, like an initiated worshipper, in the circle which is exterior to holy things, but like a hierophant, making his abode in the inmost shrines.
