בראשית, פרק מ״ו, פסוק י״ב

The family tree of Judah heading into Egypt presents a striking contrast between life and death, bridging the past and the future. The record lists his sons but pauses to mention those who have already died, while also highlighting very young grandsons. Judah had three sons from his first wife, Er, Onan, and Shelah, and two sons from Tamar, Perez and Zerah. Although Perez was very young at the time of the journey, he had already married and fathered two sons, Hezron and Hamul [ביאור שטיינזלץ]. The focus remains exclusively on Perez's children, as the sons of Zerah and Shelah were likely born later in Egypt [ברכת אשר על התורה].

A central question explores why Er and Onan are included in the count of those traveling to Egypt when they had already passed away. Commentators offer several perspectives, touching upon divine providence, moral lessons, and mystical traditions. One perspective suggests their inclusion reflects God's special affection for Judah's lineage, the future royal family. Because of this unique status, the details of their births and deaths are recorded even when not strictly necessary for the historical timeline [פרדס יוסף]. This lineage represents an unparalleled existence, destined to eventually bring forth the Messiah [אור החיים].

Another view focuses on personal morality and divine oversight. The mention of the sons' deaths serves as a reminder that divine protection is never guaranteed unconditionally. It relies on purity and ethical behavior, showing that simply having righteous parents is not enough to ensure safety [רש"ר הירש]. Others connect the deaths directly to Judah's own actions, either for marrying a foreign woman or as a strict measure of divine justice. Because Judah failed to stop the sale of Joseph and caused his father immense sadness, God reminded him of his own lost sons precisely during the joyful family reunion in Egypt, ensuring he felt a similar sadness [צאינה וראינה]. Conversely, there is an approach that judges Er and Onan more favorably. It suggests their souls were not inherently wicked, but rather they were tragically corrupted by the negative influence of the people living in the land of Canaan [אור החיים].

A final perspective views Perez's sons as a direct spiritual continuation of the sons who died. Hezron and Hamul were born specifically to fill the void left by Er and Onan, restoring the number of Judah's sons to five [העמק דבר]. Mystical traditions take this connection even deeper. Er and Onan are counted among those arriving in Egypt because, through the spiritual mechanics of levirate marriage, their souls were never truly lost. Instead, they returned to the world, reincarnated within the young boys Hezron and Hamul [רבנו בחיי, אור החיים].
