C. F. Keil and Franz Delitzsch on Deuteronomy 27:9-10

Deu 27:9-10

The words of Moses which follow in Deu 27:9 and Deu 27:10, “Be silent, and hearken, O Israel; To-day thou hast become the people of the Lord thy God,” show the significance of the act enjoined; although primarily they simply summon the Israelites to listen attentively to the still further commands. When Israel renewed the covenant with the Lord, by solemnly setting up the law in Canaan, it became thereby the nation of God, and bound itself, at the same time, to hearken to the voice of the Lord and keep His commandments, as it had already done (cf. Deu 26:17-18).
