דברים, פרק ל״ב, פסוק א׳

Moments before his passing, Moses stands to deliver his final song to the Israelites, offering both a rebuke and a prophecy for the future. In this profound setting, he does not turn to mortal men but summons all of creation to witness the covenant between God and His people. The primary approach among commentators is that Moses selected the heavens and the earth as witnesses because of their eternal nature. Unlike human beings who eventually die and cannot testify in the future, the heavens and the earth remain forever, ensuring they can refute the Israelites if they ever deny accepting the covenant [רש״י, אבן עזרא, כלי יקר]. Beyond serving as passive observers, they are the very agents who will execute reward and punishment. If the Israelites are worthy, these witnesses will provide their reward by granting dew from above and produce from below; if they sin, the heavens and the earth will be the first to punish them by withholding rain and crops [רש״י, רשב״ם, רלב״ג]. Another perspective views their selection as a moral lesson. The heavens and the earth receive neither reward nor punishment, yet they never deviate from their natural roles. Therefore, human beings, who possess intellect and are subject to divine judgment, must certainly remain faithful to their purpose and the Torah [רבנו בחיי, תורה תמימה, ביאור יש״ר]. On a mystical level, some explain that these are the original heavens and earth from the dawn of creation, now entering into the covenant with the Israelites [רמב״ן].

Moses interacts with these two realms differently, asking the heavens to lean in and listen closely, while simply stating that the earth will hear. The most common explanation ties this to Moses's spiritual proximity on the day of his death. At this final stage, he was entirely detached from physical matters, finding himself spiritually close to the heavens and distant from the earth. In human nature, one asks someone nearby to lean in and listen quietly, while raising one's voice so someone further away can hear. Because the prophet Isaiah lived in an opposite spiritual state, closer to the earthly realm, he reversed this dynamic in his own prophecies [תורה תמימה, רבנו בחיי, שפתי חכמים, חזקוני]. Another view emphasizes the difference in the required attention. Asking the heavens to listen demands deliberate effort and focus, whereas the earth, upon which Moses physically stands, hears his words automatically as a natural occurrence [אור החיים, מלבי״ם, רש״ר הירש]. Moses addresses the heavens first because they serve as the active, influencing source in nature, while the earth is the passive receiver that grows crops only as a result of what happens above [רש״ר הירש].

The style of speech Moses directs toward these witnesses also shifts, moving from firm, forceful communication for the heavens to soft, gentle expressions for the earth. This division reflects two distinct layers within both the nation and the individual. The heavens symbolize the spiritual soul as well as the leaders and great figures of the generation. Because these individuals are held to a demanding moral standard, Moses addresses them directly with exacting and firm rebuke. The earth, conversely, symbolizes the physical body and the ordinary masses. Moses approaches them with softer, appeasing language, recognizing that they require patient and comfortable guidance [כלי יקר, אור החיים, צרור המור, אברבנאל].

Notably, unlike other songs in the Torah, Moses's name is completely absent from this final address. Because this song is filled with severe rebukes and harsh punishments, Moses chose to remain anonymous, not wanting his name to be explicitly associated with words of disaster and divine anger [ריב״א, רא״ש, הדר זקנים].
