Although Parshas Mishpatim deals quite a bit with laws of property, damage, employers, employees, lost items, etc., there are also laws that deal with the purely spiritual quality of the Jew. Kashrus is one example.
There is one verse that teaches us the requirement of Shechita. It begins with the words, “And people of holiness you should be to Me, and you should not eat meat of an animal that was torn in the field . . .”. There are many mitzvos whose reason we can only define as spiritual. So, why does the Torah connect the holiness of a Jew with the prohibition of eating meat that was not properly slaughtered?
Rabbi Mordechai Kaminetzky suggests that by associating kashrus with holiness, the Torah is telling us a fact. We are what we eat. If we eat with holiness in mind, we will be holy. If we eat whatever we desire, we are removing holiness and purity. The purity of action prevents mishaps. Keep holy and you will be watched to ensure your purity. Just as kosher food, that idea is signed and sealed – by G-d.
