Moses then conveyed G‑d’s command to the Jewish people that they assemble once every seven years, during the festival of Sukot, in order to hear their king read specific passages from the Torah. Although they were commanded to study the Torah in any case, this ceremony was designed to instill renewed commitment to G‑d’s covenant with them.
Being a Jewish King
תִּקְרָא אֶת הַתּוֹרָה הַזֹּאת נֶגֶד כָּל יִשְׂרָאֵל בְּאָזְנֵיהֶם: (דברים לא:יא)
[Moses told Joshua, at the Sukot assembly, as their future “king,”] “You must read this Torah before all Israel.” Deuteronomy 31:11

The objective of this assembly was to strengthen the foundations of Jewish education and observance. We can thus fulfill this commandment nowadays firstly by “assembling” all the various facets of our personalities in order to imbue them with the knowledge and reverence of G‑d. Next, we should assemble our families periodically and strengthen each other in a spirit of family love and camaraderie. Finally, we should assemble whatever groups of people we can – whether at work, at school, in our synagogues, our extended families, our wider circle of friends, etc. – in order to influence as many people as possible to enhance their commitment to the Torah’s values and lifestyle, as based on the love and awe of G‑d.

Fulfilling this commandment to the greatest extent possible will elicit G‑d’s reciprocal response, and He will enable us to finally fulfill it in its optimal fashion, in the rebuilt holy Temple, as we listen to the Torah read to us by the ultimate Jewish king, the Messiah.1
