Respect for the past, acclimating to the future[1]
דברו אל-בני ישראל לאמר זאת החיה אשר תאכלו מכל-הבהמה אשר על-הארץ: כל מפרסת פרסת ושסעת שסע פרסת מעלת גרה בבהמה אתה תאכלו: אך את-זה לא תאכלו ממעלי הגרה וממפריסי הפרסה את-הגמל כי-מעלה גרה הוא ופרסה איננו מפריס וגו’ ואת-החזיר כי-מפריס פרסה הוא ושסע שסע פרסה והוא גרה לא-יגר טמא הוא לכם
Speak to the Children of Israel, saying: “These are the animals that you shall eat, from all the animals on the Earth: Any animal with completely split hooves, which chews its cud, you shall eat. However, these you shall not eat from those that chew their cud and have split hooves: The camel, although it chews its cud, its hooves aren’t [completely] split…And the pig, although its hooves are completely split, it doesn’t chew its cud. It is impure to you”[2]
The basic laws of kosher animals are introduced in this parsha. The rules are simple: animals with the Torah’s two kosher signs are permissible to eat. They need to have their hooves be completely split and chew their cud. If the animal has only one of these signs, like a camel or a pig, and for sure if it has neither of these signs, like a horse or a lion, then it is not kosher. However, sheep, lambs, cows, and deer, have both signs. These are permissible animals to eat.
