Sarai, Avram's wife, took Hagar the Egyptian, her handmaid, after Avram had lived ten years in the land of Kena`an, and gave her to Avram her husband to be his wife.
Sarai said to Avram, *This wrong is your fault. I gave my handmaid into your bosom, and when she saw that she had conceived, I was despised in her eyes. The LORD judge between me and you.*
but to the sons of Avraham's concubines, Avraham gave gifts. He sent them away from Yitzchak his son, while he yet lived, eastward, to the east country.
Esav went to Yishma'el, and took, besides the wives that he had, Machalat the daughter of Yishma'el, Avraham's son, the sister of Nevayot, to be his wife.
It happened, while Yisra'el lived in that land, that Re'uven went and lay with Bilhah, his father's concubine, and Yisra'el heard of it. Now the sons of Ya`akov were twelve.
