The grand assembly at Mount Ebal brought together the entire nation without a single exception. Joshua stood in the direct presence of the people and delivered the teachings of the Torah in their entirety, ensuring that no detail was left out. The audience was vast and inclusive, consisting of men, women, and young children [ביאור שטיינזלץ].
Regarding the exact content of what Joshua shared, there are different perspectives. One approach suggests that he recited all the blessings and curses recorded in the Torah [מצודת דוד]. A broader view maintains that the event was much more expansive. According to this understanding, after the Levites finished reading the blessings and curses, Joshua continued by reading every single commandment of the Torah, including both the positive obligations and the prohibitions [רד״ק, מלבי״ם].
This monumental gathering also included the converts who traveled alongside the Israelites. Their presence fulfilled the Torah's commandment to assemble the entire nation, a directive that specifically requires the participation of converts. The integration of these individuals points to a unique historical phenomenon. As the Israelites journeyed, people from other nations witnessed and heard about the miracles and wonders performed by God. Moved by these extraordinary events, they chose to walk with the Israelites, ultimately joining them and converting to their faith [רד״ק].
