What is the “right” way to perform mitzvos?
Parshas Emor lists the qualifications and regulations necessary for a kohen to serve in the Beis HaMikdash. One requirement is that a kohen must perform the avodah, the Temple service, with his right hand (Z’vachim 24a-b). This preference may not seem special, as we are familiar with the general concept of emphasizing the right side as we perform mitzvos. Even outside the context of the Beis HaMikdash, Jewish people of all tribes are supposed to use their right hands when saying Sh’ma (Orach Chayim 61:5), reciting Kiddush (ibid. 183:4), and holding food while making a blessing (ibid. 206:4), among many other examples.
