Bamidbar Rabbah 2 dives into this very idea, opening with a quote from Hosea (2:1): "The number of the children of Israel will be..." It then launches into a fascinating exploration of measure and limit. Rabbi Avin HaLevi bar Rabbi, quoting Ezra (8:34), declares, "Everything by number and by weight..." He argues that everything in existence has its measure. Water, the heavens, dust, mountains, hills—all meticulously quantified, as the prophet Isaiah tells us. Think about that for a moment. The sheer scale of it is mind-boggling.
But then comes the twist. What about Israel? Here, the rules seem to bend. According to Rabbi Avin, Israel defies easy measurement. "The one who has neither weight nor measure is Israel," he says, "who have neither weight nor measure, as it is stated: 'The number of the children of Israel will be like the sand of the sea [which cannot be measured and cannot be counted].'" Just as the sand of the sea is countless, so too is the potential and the essence of Israel.
Now, this idea is illustrated with a parable. Imagine a person skilled in three crafts: goldsmithing (considered the most sophisticated), pottery (the least), and glassblowing (somewhere in between). Depending on someone's feelings toward this person, they'd be called the son of a goldsmith (if loved), a potter (if hated), or a glazier (if viewed neutrally).
Similarly, Moses, filled with love for Israel, compares them to the stars: "Behold you are today as the stars of the heavens in abundance" (Deuteronomy 1:10). Bilam, harboring animosity, sees them as mere dust: "Who has counted the dust of Jacob?" (Numbers 23:10). And Hosea, taking a more detached view, likens them to sand: "The number of the children of Israel will be like the sand of the sea." Each metaphor reflecting a different perspective, a different value assigned to the same people.
But the metaphor of sand goes deeper. Israel is likened to sand, while other nations are likened to lime, as Isaiah (33:12) says, "Peoples will be burnings of lime." The Midrash suggests that lime, by itself, is unstable. It needs sand to give it endurance. So too, without Israel, the nations of the world would be unable to endure. Joseph’s presence saved Egypt from famine. Daniel's wisdom rescued the wise men of Babylon. There's an interdependence, a vital connection, suggested here.
Rabbi Menaḥma, in the name of Rabbi Beivai, and Rabba, in the name of Rabbi Eliezer ben Yaakov, offer another insight. Just as a hole dug in the sand fills overnight, so too, the losses suffered by Israel are eventually replenished. The thousands lost in the days of David were restored in the days of Solomon, as 1 Kings (4:20) states: "Judah and Israel were numerous, like the sand that is by the sea in abundance."
Finally, Rabbi Elazar, in the name of Rabbi Yosei ban Zimra, makes a crucial distinction: whenever Israel was counted for a specific, purposeful reason, they did not suffer a loss. This happened in the days of Moses, with the banners and the distribution of the land. But when counted without a clear purpose, as in the days of David, they suffered.
What does this all mean? Perhaps it's about potential versus actualization. Maybe it's about the dangers of objectification versus the power of purposeful action. It could be that the immeasurable nature of Israel lies not in sheer quantity, but in the boundless potential that unfolds when intention and purpose are aligned.
So, are we like the sand of the sea? Countless, resilient, and essential? Or are we something more? Something that defies easy categorization and thrives on purpose? It’s a question worth pondering, isn't it? A question that invites us to consider our own place in the grand, immeasurable scheme of things.
