The standing of the Israelites in the world serves as a direct reflection of God's own uniqueness. The deep bond between the Creator and His people was forged through unprecedented historical events, primarily the liberation from Egypt and the conquering of the promised land. Because God is completely unique in His world and the Israelites are distinct from all other nations, it is entirely fitting that they be guided by a great and decent king [רש״י].
Commentators agree that the Israelites stand apart as a remarkably unique nation. Unlike any other people, they are exceptionally fortunate and highly praised [מצודת דוד]. This distinction is clearly seen in the way God personally stepped in to save them [ביאור שטיינזלץ]. He rescued the people from slavery in Egypt specifically so they would become His own nation [רש י ומצודת דוד]. Interestingly, they were already considered His people even before this actual rescue took place [מלבי״ם]. When considering how this massive rescue was carried out, there are two ways to understand the divine action: God either worked through His messengers, Moses and Aaron, or He acted directly, with the descriptions of His actions reflecting His supreme honor [מלבי״ם].
The ultimate goal of these monumental actions was to establish and publicize God's name across the entire world [מצודת דוד וביאור שטיינזלץ]. This was achieved through massive, awe-inspiring deeds [ביאור שטיינזלץ]. However, these deeds did not end with the liberation from Egypt. They continued with the physical removal of the seven Canaanite nations to make way for the Israelites [רד ק ומצודת דוד]. The progression of these events highlights a clear and continuous process of building a nation. First came the redemption from Egyptian slavery, which was directly followed by the removal of other nations to clear a path for the chosen people [מלבי ם וביאור שטיינזלץ].
