Following a moment of profound vulnerability, a father's dignity is left shattered. The sons are forced to navigate a highly sensitive situation, and their distinct reactions not only expose their inner character but also determine the future destiny of their descendants.
Although two brothers acted together to cover their father, the primary initiative came from Shem. He invested greater effort into fulfilling this duty, driven by a deep spiritual commitment and a love for the Commandment. Japheth joined him, but his motivation stemmed primarily from basic human decency and a natural moral instinct not to leave another person in a state of degradation [מלבי״ם, העמק דבר]. It is possible that Shem initially attempted to handle the situation alone, but upon realizing he could not cover his father respectfully without assistance, he enlisted Japheth's help [העמק דבר].
The brothers specifically retrieved their father's familiar, personal garment, the very one that Ham and Canaan had stripped from him earlier, which served as the primary covering closest to the skin [ביאור יש״ר, הכתב והקבלה]. To execute the task with the utmost respect, they placed the garment upon both of their shoulders, each carrying one end [אבן עזרא]. A unique perspective suggests a different dynamic: Shem and Japheth actually forced Ham and Canaan to carry the garment on their shoulders and enter the tent. This was done to instill a sense of shame in the transgressors and to teach them the proper reverence due to a father [ביאור יש״ר].
As they approached, the brothers adopted an unnatural method of movement, walking backward [אבן עזרא]. Yet, because this awkward motion was performed deliberately to preserve a father's honor, it is considered a perfect and elevated form of walking. It parallels the reverence of the High Priest, who walks backward when exiting the Holy of Holies out of awe [תורה תמימה]. When they reached the critical moment of draping the garment, they naturally had to turn their bodies toward their father. To ensure they remained shielded from the disgrace, they kept their faces turned away and even placed their hands over their eyes [רש״י, ספורנו, לבוש האורה, דברי דוד]. Beyond physical protection, there was a profound spiritual caution at play. The human face reflects the image of God, and the righteous brothers refused to expose their faces to impurity and degradation, even with their eyes tightly shut [אלשיך].
On a psychological level, their deliberate avoidance of sight demonstrated a refusal to focus on their father's shortcomings. While Ham had stared at the disgrace and publicized it—revealing a similar internal flaw within himself—Shem and Japheth concentrated entirely on rectifying the situation without dwelling on another person's shame [בעל שם טוב]. This act of covering also highlights a fundamental distinction between humanity and the animal kingdom. The inherent sense of shame regarding nakedness defines the human condition. Consequently, even when dealing with nations that behave wildly and lack clothing, they remain undeniably human, and the laws forbidding the recitation of the Shema prayer while facing nakedness apply fully in their presence [תורה תמימה].
The actions of the brothers resulted in precise, corresponding consequences for their descendants. Ham, who disgraced his father, was destined to have his descendants led into exile naked and barefoot. Japheth, who protected his father's physical dignity, earned the reward of a respectful physical burial for his descendants. Shem, who acted purely for the sake of Heaven, earned the spiritual reward of his descendants wrapping themselves in the fringed prayer shawl [רש״י, גור אריה].
This specific reward for Shem presents a conceptual challenge, as a separate tradition attributes the Commandment of the fringes to the merit of Abraham. The primary approach among commentators harmonizes these ideas by viewing them as a combined merit. Shem's act of covering granted the Israelites the foundational prayer shawl and its white threads, while Abraham's merit added the specific blue thread [מזרחי, שפתי חכמים, דברי דוד]. Another perspective maintains that Shem secured the spiritual reward for his descendants in a general sense, but it remained uncertain which specific lineage would receive it until Abraham's successful trials secured the Commandment specifically for his direct offspring [הטור הארוך, לבוש האורה, פענח רזא]. Alternatively, Shem's merit simply granted his descendants fine, honorable clothing in general, leaving the actual Commandment of the fringes to be earned entirely by Abraham [ריב״א].
