The mystery of the red heifer[1]
וידבר יקוק אל-משה ואל אהרן לאמר: זאת חקת התורה אשר-צוה יקוק לאמר דבר אל-בני ישראל ויחקו אליך פרה אדומה תמימה וגו’
Hashem spoke to Moshe and Aharon, saying: “This is the decree of the Torah, that Hashem commanded to say: ‘Tell the Jewish people to take towards you a perfectly[2] red heifer’”[3]
The Torah teaches us[4] about the laws of spiritual impurity caused by contact with the dead. There is a single remedy for a person to purify themselves: the ashes of a perfectly red heifer. The Torah details its preparation, and how and when it is applied to a person. We are taught that this mitzvah is the prototypical chok, or decree, from Hashem. This category of mitzvos are those to which the underlying reasoning alludes us. What is the chok of the red heifer? All those who prepare and apply the ashes of the red heifer become spiritual impure, whereas the person who is treated with them becomes pure[5]. How could these two opposites coexist? This is something only[6] Moshe understood fully[7], until the End of Days when its secrets will be revealed to all[8]. For us now, it is viewed as a chok; something we have to accept and await the day when we will finally understand it[9]. One could ask a basic question on this idea: since the red heifer does in fact have an underlying reason, why is it eluded from us? Why reveal it only to Moshe, especially since it will eventually be explained to everyone[10]?
