Parshah Nitzavim

You stand upright this day, all of you, before the L-rd your G-d: your heads, your tribes, your elders, and your officers, and all the men of Israel; your little ones, your wives, and your stranger that is in your camp, from the hewer of your wood to the drawer of your water (Deuteronomy 29:9-10)

Our sages have said: "All Israel are guarantors for each other" (Talmud, Shevuot 39a). But a person cannot serve as a guarantor unless he is more resourceful in some way than the one he is guaranteeing. For example, a poor man obviously would not be accepted as a guarantor for a rich man's loan. So if the Talmud says that all Jews serve as guarantors to each other, this means that in every Jew there is a quality in which he or she is superior to all others.
