Like terumot and ma’asrot, the mitzva of ḥalla is tied to Eretz Yisrael, as the Torah states: “When you come to the land to which I am bringing you… when you eat of the bread of the land, you shall set aside a gift for the Lord” (Bamidbar 15:18–19). These mitzvot also depend on the Jewish people’s national presence in the Land. They apply by Torah law only when most of Israel lives there, as the Sages derive from the phrase “when you come to the land”: “when all of you come, and not when only some of you come” (Ketubot 25a). This teaches a fundamental principle: the holiness embedded in nature is revealed when the people of Israel, created to reveal the word of God, live in Eretz Yisrael, the Land through which holiness is meant to be revealed.
There is, however, an important difference between ḥalla and terumot and ma’asrot. Terumot and ma’asrot are determined by the produce itself: one must still separate terumot and ma’asrot from fruit or grain that grew in Eretz Yisrael and had its processing completed there, even if it is later taken outside the Land (above, 8:9). Ḥalla, by contrast, is determined by where the dough is made. One must separate ḥalla from dough kneaded in Eretz Yisrael even when the flour came from grain grown outside the Land; by Torah law, dough kneaded outside the Land is exempt from ḥalla, even if the flour came from grain grown in Eretz Yisrael (Yerushalmi, Ḥalla 2:1). With terumot and ma’asrot, the sanctity follows produce that grew in the Land. With ḥalla, the sanctity is attached to the human work done in the Land. Even if the grain itself grew elsewhere, once Jews knead it into dough in Eretz Yisrael, that creative act must be sanctified through the separation of ḥalla.
After the destruction of the First Temple and Israel’s exile from the Land, most Jews no longer lived in Eretz Yisrael, and the Torah obligation of ḥalla came to an end. Even with the building of the Second Temple, the biblical obligation was not restored, because most of the Jewish people remained in exile. Therefore, the Sages of the Great Court at the beginning of the Second Temple period, led by Ezra the Scribe, enacted that terumot, ma’asrot, and ḥalla continue to be separated by rabbinic law even when most of Israel is not living in its Land.
The Sages extended the mitzva even further with respect to ḥalla, requiring Jews outside the Land to separate it from their dough so that the mitzva would not be forgotten. They did not make a similar enactment for terumot and ma’asrot, because their obligation is tied directly to produce grown in the Land. Ḥalla is different: although it too is rooted in Eretz Yisrael, its obligation begins when a person kneads dough. In that respect, it resembles mitzvot that depend on human action rather than on the soil itself, and the Sages were therefore able to extend it even to dough prepared outside the Land (Tosafot, Kiddushin 36b; below, 12:10).
This enactment carries a deeper meaning as well. Because Israel fulfilled the mitzva of ḥalla in Eretz Yisrael throughout the First Temple period, the Sages were able to draw its holiness outward, extending the obligation to dough prepared by Jews even outside the Land. In this way, Jewish creativity in the Diaspora remains bound to the holiness that begins in Eretz Yisrael and will ultimately spread from there to the entire world.
