The Tzitz and the Bnei Yisrael
וְעָשִׂיתָ צִּיץ זָהָב טָהוֹר וּפִתַּחְתָּ עָלָיו... קֹדֶשׁ לַה'
You shall make a tzitz (headplate) of pure gold, and you shall engrave upon it… “Holy to Hashem” (28:36)
The pasuk does not specify exactly what is “Holy to Hashem”. Does this refer to the tzitz itself? If so, in what way is the tzitz more “holy to Hashem” than any of the other bigdei kehunah (priestly garments)?
The Meshech Chochmah explains that the words on the tzitz need to be taken in the context of other words which are written on the bigdei kehunah. On two sets of stones worn by the Kohen Gadol – the Avnei Shoham on the Efod and the Avnei Miluim on the Choshen – are engraved the names of the twelve tribes if Israel. The Tosefta informs us that all the bigdei kehunah are inter-connected and inter-dependent, i.e. the mitzvah is performed by the Kohen Gadol specifically wearing all of them. As such, they are to be taken as a single composite unit. As such, it is conjunction with these names that the tzitz is to be read, for it is to these twelve tribes that it is referring when it says “Holy to Hashem,” as the pasuk states “קֹדֶשׁ יִשְׂרָאֵל לַה' – Israel is Holy to Hashem”!
In the World of Korbanos – Halachic Ramifications
It emerges that the two words engraved on the tzitz are a statement about the holiness of the Jewish People. Indeed, says Meshech Chochmah, this is something that is reflected in the halachic function of the tzitz, which is to atone for certain types of tumah that may occur in the bringing of korbanos. In the words of Chazal: “הציץ מרצה – the tzitz expiates.” However, the Gemara states that this effects pertains only to the korbanos of the Bnei Yisrael. If a gentile should bring a korban and it becomes tamei, the tzitz does not atone for it. If the effect of the tzitz is self-contained, relating to the korbanos themselves, what difference should there be as to whose korban it atones for? Once we appreciate, however, that the tzitz is expressing the kedushah of the Bnei Yisrael, we will understand why its effect is limited to their korbanos.
Moreover, commenting on the words in Parshas Shelach, “כָּכֶם כַּגֵּר יִהְיֶה לִפְנֵי ה' – As for you, so too, for the convert before Hashem,” the Sifrei explains that this comes to include converts in the category of those whose korbanos can be atoned for by the tzitz. Seemingly, such an exposition should not be necessary, for having converted and become part of the Jewish People, do they not naturally partake of all the halachos that relate to the Jewish People? Once we appreciate, however, that the effect of the tzitz is a function of the kedushah of the twelve tribes of Israel, we may have thought that it does not apply to someone who is not actually descended from one of those tribes. Therefore, the pasuk informs us that it apples to anyone who belongs to the People of Israel.
The Meshech Chochmah proceeds to explain in this light another episode where we the tzitz played an active role. Toward the end of Chumash Bamidbar, Bnei Yisrael waged war against Midian, capturing many of those who had been involved in enticing the People to immorality. The Gemara explains that the means through which they detected which of the Midianite daughters should be put to death was by passing them in front of the tzitz, whereby those who were culpable visibly changed color. Why was this process performed by using the tzitz specifically? Since the actions of the daughters of Midian led to a profanation of the sanctity of Bnei Yisrael, their liability was determined by the tzitz which is dedicated to proclaiming that sanctity.
“Remembrance Stones for Bnei Yisrael”
This idea will give us deeper insight into a term which is used in conjunction with both these sets of stones, namely, that of זכרון – remembrance. The Avnei Shoham are referred to as “אַבְנֵי זִכָּרֹן לִבְנֵי יִשְׂרָאֵל – remembrance stones for Bnei Yisrael,” and the pasuk subsequently states that the stones on the Choshen shall be “לְזִכָּרֹן לִפְנֵי ה' תָּמִיד – as a remembrance before Hashem, always.”
The Gemara informs us that as surely as we wear tefillin in which are written pesukim proclaiming that Hashem is our One and Only God, so too, Hashem, so to speak, wears tefillin in which is stated “ומי כעמך ישראל גוי אחד בארץ – Who is like Your nation, Israel, one People in the land!” Once we appreciate that the words “קודש לה'” on the tzitz are written in reference to the tribes of Israel engraved on the stones, we can understand that the stones are in fact a representation of the idea of Hashem’s tefillin which proclaim that the Jewish People are “Holy to Hashem”. In this light, the two sets of stones correspond to the two types of tefillin: the Avnei Shoham on the shoulders near the head – corresponding to the shel rosh, and the Avnei Miluim resting on the heart, corresponding to the shel yad.
Moreover, says Meshech Chochmah, with this in mind we can understand on a new level the opinion of R’ Yehoshua ben Levi, cited in the Yerushalmi, that the eight bigdei kehunah are to be worn by the Kohen Gadol only on Shabbos and Yom Tov. What is behind this qualification? Rather, during the week, when the Jewish People are wearing their tefillin, that is sufficient to evoke Hashem’s connection with us represented by His tefillin. On Shabbos and Yom Tov, when tefillin are not worn by Israel, the idea of Hashem’s tefillin is evoked by the two sets of remembrance stones worn by the Kohen Gadol as part of the bigdei kehunah.

 It is most interesting to consider in this regard the exposition of the Gemara (Yoma 6b) which derives from the word “תמיד - always” as stated with regards to the tzitz (pasuk 38) that one’s attention should not waver while he is wearing tefillin!
