The foundation of the unique relationship between God and the Israelites is rooted in the historical and spiritual journey of the nation's founding father. This journey marks a profound shift in how God interacts with the world, moving from natural, everyday laws to a miraculous, supernatural guidance reserved for chosen individuals [מלבי״ם]. God selected him to be the very first vessel for this extraordinary way of life.
When he was first chosen by God, he was still known by his original name [ביאור שטיינזלץ]. His departure from his homeland was far more than a simple geographical relocation; it was a dramatic divine intervention and rescue. According to ancient tradition, he was thrown into a fiery furnace by Nimrod for standing against the idol worship of his society, and God miraculously saved Him [מצודת דוד, מלבי״ם]. Through this ultimate act of self-sacrifice, he purified himself completely, transforming his inner nature into absolute good [חומת אנך]. The purpose behind this miraculous rescue was to guide him toward a specific, chosen land, laying the groundwork for his descendants to eventually become a treasured people set apart from all other nations [רלב״ג].
The completion of this spiritual process occurred later, once he was already living in the Land of Israel, when God gave him a new name [ביאור שטיינזלץ]. This new identity reflected the immense greatness he had achieved as the father of many nations. It also served as a lasting sign that his chosen descendants would inherit the land and merit having the Divine Presence rest among them [רלב״ג, מצודת דוד, מלבי״ם].
