The tragedy of Joseph’s sale opens with the words: And Joseph’s brothers went to graze their father’s flock at Shechem. The text of the Bible contains some dots over this verse, teaching us, Rashi explains, that really they went “to graze themselves,” ie to enjoy themselves – they said they were working but really they went out to have a good time. Rabbi Yehuda Leib Ginsburg explains that work saves a person from sin and had the brothers truly been busy working they would never have had the time to fall into the sin of selling their brother.
