Yehoshua establishes a monument from twelve stones taken from the Yarden, each representing one tribe. Rabbi Shlomo Aviner notes that this monument represents the “unity but not uniformity” of the Jewish people. There are twelve individual stones, which symbolize the diversity of the tribes. But the stones are not scattered. Together, they form a unified monument. This “unity but not uniformity” is one of the keys to Israel’s success. Israel is an extremely diverse country. Yet her people have unified to create a society that is truly a “light unto the nations.”
