Chayei Sarah 5773

Avraham remarries at the end of the parsha to Keturah. Rashi says this was Hagar and was called Keturah because her actions were nice as ketores (the incense). But didn't Rashi say last week she went back to doing avodah zarah (idolatry) after leaving Avraham? The Kli Yakar explains that Hagar had done teshuvah and the actions of a ba'al teshuvah become good and are like a nice smell (kivyachol) for Hashem, just like the ketores is. Avraham had named her Keturah to tell people she had done teshuvah.
