bilhah

The Testament of Naftali, part of the Dead Sea Scrolls, says that Bilhah and Zilpah's father was named Ahotay. He was taken into captivity but redeemed by Laban, Rachel and Leah's father, and he gave Ahotay a wife named Hannah, 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 {see also, Pirke De-Rabbi Eliezer, xxxvi.}.
Genesis 35:22 says "And it was during the stay of Israel in that land, and Reuben went and lay with Bilha, his father's concubine, and Israel heard..."^[2] As a result of this adultery, he lost the respect of his father, as Genesis 49:4 says: "Turbulent as the waters, you will no longer excel, for you went up onto your father’s bed, onto my couch and defiled it."
However, Rashi, an 11th-century commentator, interprets the story differently. He suggests that, as long as Rachel was alive, Jacob kept his bed in her tent and visited the other wives in theirs. When Rachel died, Jacob moved his bed into the tent of Bilhah, who had been mentored by Rachel, to retain a closeness to his favourite wife. However, Reuben, eldest son of Leah, felt that this move slighted his mother, who was also a primary wife, and so he moved Jacob's bed into his mother's tent. This invasion of Jacob's privacy was viewed so gravely that the Bible equates it with adultery, and lost Reuben his first-born right to a double inheritance.^[3]
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 Bilhah and surrounding territories prior to the reign of David
