In this week’s parshah the Torah teaches us which animals are kosher to eat and which are not. The Torah says that the pig, although it has split hooves, is not kosher since it does not chew its cud. The medrash on this pasuk says that the reason that the pig is called “chazir” is because in the future Hashem will return (lehachzir) the pig to Bnei Yisrael and permit it to be eaten.
In this week’s parshah the Torah teaches many of the halachos of the korbanos. Each of the korbanos has a limited amount of time when they may be eaten, after which they become nosar and forbidden.
