Bilhah (בִּלְהָה "unworried", Standard Hebrew: Bilha, Tiberian Hebrew: Bīlhā) is a woman mentioned in the Book of Genesis. Genesis 29:29 describes her as Laban's handmaiden (שִׁפְחָה), who was given to Rachel to be her handmaid on Rachel's marriage to Jacob. When Rachel failed to have children, Rachel gave Bilhah to Jacob like a wife to bear him children. Bilhah gave birth to two sons, whom Rachel claimed as her own and named Dan and Naphtali. Genesis 35:22 expressly calls Bilhah Jacob's concubine, a pilegesh. When Leah saw that she had stopped having children, she took her servant Zilpah and gave her to Jacob like a wife to bear him children as well.
The apocryphal Testament of Naftali says that Bilhah and Zilpah's father was named Rotheus. He was taken into captivity but redeemed by Laban, Rachel and Leah's father. Laban gave Rotheus a wife named Euna, who was the girls' mother. On the other hand, the early rabbinical commentary Pirkei De-Rabbi Eliezer and other rabbinic sources (Midrash Rabba and elsewhere) state that Bilhah and Zilpah were also Laban's daughters, through his concubines, which would make them half-sisters to Rachel and Leah. Scholars believe that these attempts to make Bilhah and Zilpah appear biologically related to Abraham's family were a result of anti-foreign views in the postexilic period. It appears more likely that they were foreign like Tamar and Asenath, who were considered to be 'secondary Matriarchs'.
