Thematic Bible: Emulation

When Rachel saw that she was not bearing Jacob [any children], she envied her sister. "Give me sons, or I will die!" she said to Jacob. Jacob became angry with Rachel and said, "Am I in God's place, who has withheld children from you?" Then she said, "Here is my slave Bilhah. Go sleep with her, and she'll bear [children] for me so that through her I too can build [a family]." read more.
So Rachel gave her slave Bilhah to Jacob as a wife, and he slept with her. Bilhah conceived and bore Jacob a son. Rachel said, "God has vindicated me; yes, He has heard me and given me a son," and she named him Dan. Rachel's slave Bilhah conceived again and bore Jacob a second son. Rachel said, "In [my] wrestlings with God, I have wrestled with my sister and won," and she named him Naphtali. When Leah saw that she had stopped having children, she took her slave Zilpah and gave her to Jacob as a wife. Leah's slave Zilpah bore Jacob a son. Then Leah said, "What good fortune!" and she named him Gad. When Leah's slave Zilpah bore Jacob a second son, Leah said, "I am happy that the women call me happy," so she named him Asher. Reuben went out during the wheat harvest and found some mandrakes in the field. When he brought them to his mother Leah, Rachel asked, "Please give me some of your son's mandrakes." But Leah replied to her, "Isn't it enough that you have taken my husband? Now you also want to take my son's mandrakes?" "Well," Rachel said, "you can sleep with him tonight in exchange for your son's mandrakes." When Jacob came in from the field that evening, Leah went out to meet him and said, "You must come with me, for I have hired you with my son's mandrakes." So Jacob slept with her that night. God listened to Leah, and she conceived and bore Jacob a fifth son. Leah said, "God has rewarded me for giving my slave to my husband," and she named him Issachar. Then Leah conceived again and bore Jacob a sixth son. "God has given me a good gift," Leah said. "This time my husband will honor me because I have borne him six sons," and she named him Zebulun. Later, Leah bore a daughter and named her Dinah. Then God remembered Rachel. He listened to her and opened her womb. She conceived and bore a son, and said, "God has taken away my shame." She named him Joseph: "May the Lord add another son to me."
