Ray > how is chasing away the mother for no tachlis showing mercy?
How is this mitzva is so special, as it is one of the 74 mitzvos in Ki Tetse. More effort is required to catch a girl in the war, raise a glutton kid, lo aleinu, hang stoned criminals, build a fence on the roof, get married and then tell lashon haro about her, then divorce her, and then not divorce her depending on circumstances, buy a portable toilet before a trip, get interest from non-Jews, do halitza and remember Amalek.
