I heard a nice vort on purim that’s related to this. It says in Megillas Esther, ??????? ???? ???? ???? ????? ????. We also say these words in Havdala. Why do we say it in Havdala? The gemara in Megilla tes zayin amud beis says this pasuk refers to Torah, Mila, Yom Tov and Tefilin. These things make us different than Goyim. We have these mitzvos and the Goyim don’t. In fact, if a goy does any of these things, he’s chayiv misa. Yom tov also refers Shabbos. The Gemara says ??? ???? ???? ????. This is why we say it in Havdala, which means seperation. This Pasuk refers to how we are seperate from the Goyim.
Have a good Shabbos!
