Philo: The Special Laws, I

XXI. (108) But besides this, injunctions are given to the particular and inferior priests concerning their marriages, which are the very same in most points, which are given to those who have the supreme priesthood. But they are permitted with impunity to marry not only maidens but widows also; not, indeed, all widows, but those whose husbands are dead. For the law thinks it fitting to remove all quarrels and disputes from the life of the priests. And if they had husbands living there very likely might be disputes from the jealousy which is caused by the love of men for women.

But when the first husband is dead, then with him the hostility which could be felt towards the second husband dies also. (109) And even on other accounts he might have thought that the high priest ought to be of superior purity and holiness, as in other matters so also in the connection of marriage, and on this account it may have been that God only allowed the high priest to marry a virgin. But to the priests of the second rank he remitted something of the rigour of his regulations concerning the connection with women, permitting them to marry women who have made trials of other husbands.
