על החוקים לפרטיהם, ספר א כ״אOn the Special Laws, Book I 21

א׳
1[108] As for the subordinate  priests, while the other marriage regulations are the same for them as for those who hold the highest priesthood, they are permitted to wed with immunity not only virgins but widows,  though only such as have lost their husbands by death. This limitation is due to the desire of the law to remove animosities and feuds from the lives of the priests. While the first husband lives, quarrels might be engendered by the feminine proclivity to jealousy.  His death carries with it the death of any hostility to the second husband.

2[109] As for the distinction between priests and high priests, the view of the law was that the greater sanctity and purity required of the latter in all other matters should be extended to his choice of a partner in marriage, and therefore it forbade him to take to wife any but a maiden. But to those of the second rank it made concessions as to their relations with women and permitted them to espouse such as had had experience of other husbands.
