בראשית, פרק ל״ה, פסוק כ״ה

The family record of Jacob's children details the sons born to the maidservants, focusing on their ongoing relationship with the matriarchs of the nation. Bilhah's identity as a maidservant was not merely a historical fact about her original social standing. Instead, it reflected the practical, everyday reality of their household. Bilhah continued to treat Rachel with the respect and submission of a servant toward her mistress, just as Zilpah maintained the same dynamic with Leah [העמק דבר].

Through Bilhah, the family expanded with the birth of her two sons, Dan and Naphtali [ביאור שטיינזלץ].
