Note 174 — II. OUR DUTIES. (continued 4)
Reading edition
There is a kind of obligatory marriage (יבום) and or obligatory divorce (חליצה), viz., with regard to the widow of a deceased brother who has died without issue (Deut. xxv. 5–10). Since the abolition of polygamy174 by Rabbenu Gershom (eleventh century) the obligatory marriage has almost disappeared, and the obligatory divorce (חליצה) must take place before the widow can marry again.175
