בראשית, פרק ל״ח, פסוק ז׳

The sudden passing of a young man destined for greatness raises immediate questions. Though the exact nature of his wrongdoing is not explicitly detailed, the narrative leaves clues that allow for a deeper understanding of his actions and the divine judgment he faced. His behavior was deemed evil in the eyes of God, pointing to a hidden sin committed in absolute privacy and known only to the Creator [ספורנו, רד״ק]. By looking at the later fate of his brother, who suffered the exact same divine punishment, commentators conclude that both shared the same offense of spilling their seed [רש״י, תורה תמימה, ביאור יש״ר]. A subtle linguistic hint reinforces this concept, as the young man's name is an exact reversal of the Hebrew word for bad. By reversing his natural purpose and destiny, he brought about his own downfall and lost his existence [רא״ש, בכור שור].

The motive behind this private act requires exploration. Unlike his younger brother, who later had a clear reason to avoid producing an heir, the firstborn's intentions were different [מזרחי, שפתי חכמים]. The primary approach among commentators is that he acted out of vanity, wishing to prevent his wife from conceiving so that her physical beauty would not be compromised by pregnancy. Another perspective suggests his actions stemmed from pure selfishness, as he desired physical pleasure but refused to accept the burden and effort of raising children [בכור שור]. As a direct result of these choices, his wife remained a virgin, a crucial detail that would significantly shape her future interactions with his father [בכור שור, חזקוני].

The severity of the divine response prompts further inquiry into why such a strict penalty was applied. As the firstborn of his family, this young man was destined to be the founding father of the Davidic royal dynasty. Because of this monumental destiny, he was judged by a profoundly strict standard. While an ordinary person might not incur a heavenly death penalty for such an act, his behavior rendered him fundamentally unfit to establish a royal lineage [העמק דבר, מלבי״ם].

The timing of his death also presents a challenge, as heavenly punishment is typically reserved for those over the age of twenty. Some explain that a younger person can be judged if his wisdom matches that of a twenty-year-old, or perhaps he was indeed older than assumed [הטור הארוך]. Alternatively, God may have ended his life early as an act of mercy, stopping him before his sin became an ingrained habit, or his death was a combination of his personal failing and a consequence of an incomplete Commandment in his father's past [פרדס יוסף]. Nevertheless, a prominent approach stresses that he died exclusively for his own sin. This clarifies that his death was not a delayed punishment for his father's role in the sale of his brother, especially since his father had actually saved that brother's life. Ultimately, the loss of children was an exceptionally rare tragedy within the patriarchal family. It brought immense grief to his grandfather, who perceived the event not merely as a natural cause for sorrow, but as a severe divine judgment [רמב״ן, הטור הארוך, ביאור יש״ר].
