The people were able to complete the divorce proceedings in three months (vv. 9, 17). A total of 113 Israelites had married and now divorced their foreign wives, only a fraction of the total number of Jews then living in Judah. Of these, 16 were priests and 10 were Levites, about 25 percent of the total. Perhaps Jewish women had not married Gentile men. A more likely possibility is that since women could not divorce their husbands in Israel the Jewish women who had married Gentiles did not get divorces.
