Milcah

Milkāh, related to the Hebrew word for "queen") was the daughter of Haran and the wife of Nahor, according to the genealogies of Genesis. She is identified as the grandmother of Rebecca in biblical tradition, and some texts of the Midrash have identified her as Sarah's sister.

According to Genesis Chapter 22, Milcah and Nahor have eight children: Huz, Buz, Kemuel, Chesed, Hazo, Pildash, Jidlaph, and Bethuel. Milcah’s son Bethuel moves to Padan-aram (also called Aram-Naharaim) and fathers Rebekah.^[9] Milcah’s granddaughter Rebekah eventually marries Milcah’s nephew Isaac^[10] and gave birth to Jacob^[11] who became Israel.^[12] There is a midrash that Milcah was the forbearer of all prophets in the non-Jewish world.

Milcah marries Nahor

Gen 11:29  And Abram and Nahor took them wives: the name of Abram's wife was Sarai; and the name of Nahor's wife, Milcah, the daughter of Haran, the father of Milcah, and the father of Iscah. 

Milcah bares children to Nahor

(Gen 22:20)  And it came to pass after these things, that it was told Abraham, saying, Behold, Milcah, she hath also born children unto thy brother Nahor;

(Gen 22:21)  Huz his firstborn, and Buz his brother, and Kemuel the father of Aram,

(Gen 22:22)  And Chesed, and Hazo, and Pildash, and Jidlaph, and Bethuel.

(Gen 22:23)  And Bethuel begat Rebekah: these eight Milcah did bear to Nahor, Abraham's brother.
