Abraham's life was defined by a series of profound trials. After successfully standing firm through them all, his absolute loyalty was fully revealed, proving that his heart was completely faithful to God [מלבי״ם]. As a direct result of this unwavering devotion, a binding covenant was actively established with him [רש״י, ביאור שטיינזלץ]. The central purpose of this agreement was to grant him the land of Canaan, a territory uniquely suited for miraculous divine providence [מלבי״ם].
The transmission of the land is framed as a twofold act of giving. This repetition is understood by some simply as a standard biblical style, ensuring the flow of the idea remains clear across a lengthy thought [מצודת דוד]. Others, however, see a profound dual meaning in the process. The initial act of giving represents the promise and destiny bestowed upon Abraham himself, while the second refers to the practical, physical inheritance of the land by his descendants who would eventually arrive to take possession of it [מלבי״ם].
Generations later, God fulfilled this promise, demonstrating that His word stands forever [חומת אנך, מצודת דוד, ביאור שטיינזלץ]. This fulfillment marks the historical turning point where the ancient covenant transitioned into living reality [מלבי״ם]. Ultimately, the transfer of the land to the Israelites highlights God's perfect justice [ביאור שטיינזלץ]. Taking the territory from the Canaanite nations was not an act of injustice, but rather a measure of absolute righteousness, as those nations were expelled strictly as a consequence of their own wickedness [מלבי״ם].
