Bilhah

[1] Bilhah gave birth to two sons, whom Rachel claimed as her own and named Dan and Naphtali.

[c] 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.

[3][4][d] 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.

In the Books of Chronicles, Shimei's brothers were said to have lived in a town called Bilhah and surrounding territories prior to the reign of David.

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.
