Bilhah (בִּלְהָה "unworried", Standard Hebrew Bilha, Tiberian Hebrew Bilhâ) is a person mentioned in the Book of Genesis.Genesis 29:29 describes her as Laban's handmaid, 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 "to wife" to bear him children. Bilhah gave birth to two sons, who Rachel claimed as her own and named Dan and Naphtali.Genesis 35:22 expressly calls Bilhah Jacob's concubine, a pilegesh.
The 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, who gave Rotheus a wife named Euna, who was their mother. Rabbinic sources (Midrash Raba, and elsewhere), on the other hand, state that Bilhah and Zilpah were also Laban's daughters, through his concubines, making them half-sisters to Rachel and Leah.
Bilhah is said to be buried in the Tomb of the Matriarchs in Tiberias.
In the Book of Chronicles, Shimei's brothers were said to have lived in a town called Bilhah and surrounding territories prior to the reign of David.
Reuben was Jacob's (Israel) eldest son with Leah. Genesis 35:22 says "And it came to pass, while Israel dwelt in that land, that Reuben went and lay with Bilhah his father's concubine; and Israel heard of it." As a result of this adultery, he lost the respect of his father, who said: "Unstable as water, have not thou the excellency; because thou wentest up to thy father's bed; then defiledst thou it--he went up to my couch."
