Solid Backing
אַתֶּם נִצָּבִים הַיּוֹם כֻּלְּכֶם לִפְנֵי ה’ אֱלֹקֵיכֶם רָאשֵׁיכֶם שִׁבְטֵיכֶם זִקְנֵיכֶם וְשֹׁטְרֵיכֶם כֹּל אִישׁ יִשְׂרָאֵל: טַפְּכֶם נְשֵׁיכֶם וְגֵרְךָ אֲשֶׁר בְּקֶרֶב מַחֲנֶיךָ מֵחֹטֵב עֵצֶיךָ עַד שֹׁאֵב מֵימֶיךָ: לְעָבְרְךָ בִּבְרִית ה’ אֱלֹקֶיךָ (דברים כט, ט-יא)
You are standing today before Hashem your G-d: the leaders of your tribes, your elders and your officers, every man of Israel; your young children, your women, and your convert who is within your camp, your woodcutters and your water drawers. so that you may enter the covenant of Hashem your G-d (Devarim 29:9-11)
The commentaries explain that the purpose of this covenant was to enlist every Jew as a guarantor that his fellow Jews will observe the Torah (see Ohr Hachaim; Rashi on 29:28). As our Sages taught, “All of Israel are guarantors for one another” (Talmud, Shevuos 39a); meaning, every Jew bears personal responsibility for his fellow.
A guarantor is presumably in a better position than the person he is backing, which is what makes him more dependable than the person whose commitment he is standing behind. For example, a wealthy person could serve as a guarantor for a poor person’s loan, but not vice versa. Hence, if “all of Israel are guarantors for one another,” evidently, every Jew, from “the leaders of your tribes” down to “your water drawers,” (as enumerated here by the Torah,) has a unique strength that qualifies him as a guarantor for the others.
This can be understood in light of the Alter Rebbe’s teaching (Likutei Torah, Nitzavim 44a) that the Jewish nation is “one complete figure,” comparable to a human body in which every limb and organ completes and complements the other. The head and brain are ostensibly “superior” to the other parts of the body, yet the legs support and give mobility to the entire body, including the head. Similarly, every single Jew has a quality with which he, and only he, can serve as the guarantor for the rest of the Jewish nation, due to his extraordinary strength in that particular area of Jewish observance.
