Daily Aliya for Re’eh, Revii (4th Aliya)
Aliya Summary: As G‑d’s children, we are forbidden to deface our bodies with tattoos or via other forms of mutilation. This section then provides a list of kosher animals and non-kosher fowl. We are also given signs to distinguish between kosher animals and fish and their non-kosher counterparts. The section concludes with the prohibitions against eating meat from an animal which was not properly slaughtered, and against cooking meat with milk.
In the spirit of the positive commandment to check for kashrut, it appears that this Mitzvah does not only include checking animals, birds and fish for signs, but looking for the kashrut symbol on packaged products or the kashrut certificate in restaurants.
