B'resheet 30:1 Now when Rachel saw that she bore Ya'akov no children, she became jealous of her sister; and she said to Ya'akov, "Give me children, or else I die."
The corresponding Hebrew letter to this chapter is Chet - new beginning; new life; grace or favor; a metaphysical letter above this existence.
B'resheet 30:2-3 Then Ya'akov's anger burned against Rachel, and he said, "Am I in the place of G-d, who has withheld from you the fruit of the womb?" And she said, "Here is my maid Bilhah, go in to her, that she may bear on my knees, that through her I too may have children."
Each of the patriarchs Avraham, Yitz'chak, and Ya'akov each had wives that had problems bearing children. Ya'akov followed his grandfather's example and got involved with his wives maids. This did not solve the problem; it only made the situation worse. His father Yitz'chak would have been the better example to follow. When Rivkah was unable to bear children, Yitz'chak prayed and asked G-d to allow her to bear children.
B'resheet 30:4-6 So she gave him her maid Bilhah as a wife, and Ya'akov went in to her. And Bilhah conceived and bore Ya'akov a son. Then Rachel said, "G-d has vindicated me, and has indeed heard my voice and has given me a son." Therefore she named him Dan.
Dan - means "He judged".
B'resheet 30:7-8 And Rachel's maid Bilhah conceived again and bore Ya'akov a second son. So Rachel said, "With mighty wrestlings I have wrestled with my sister, and I have indeed prevailed." And she named him Naftali.
Naftali means "my wrestling"
B'resheet 30:9-11 When Leah saw that she had stopped bearing, she took her maid Zilpah and gave her to Ya'akov as a wife. And Leah's maid Zilpah bore Ya'akov a son. Then Leah said, "How fortunate!" So she named him Gad.
Gad means "good fortune"
B'resheet 30:12-13 And Leah's maid Zilpah bore Ya'akov a second son. Then Leah said, "Happy am I! For women will call me happy." So she named him Asher.
Asher - means Happy.
Her we see the names and BEGINNING of the 12 tribes of Israel. Again regardless of the actions of Ya'akov the L-rd still blessed him.
B'resheet 30:14-16 Now in the days of wheat harvest Re'uven went and found mandrakes in the field, and brought them to his mother Leah. Then Rachel said to Leah, "Please give me some of your son's mandrakes." But she said to her, "Is it a small matter for you to take my husband? And would you take my son's mandrakes also?" So Rachel said, "Therefore he may lie with you tonight in return for your son's mandrakes." When Ya'akov came in from the field in the evening, then Leah went out to meet him and said, "You must come in to me, for I have surely hired you with my son's mandrakes." So he lay with her that night.
Mandrakes are known as "love apples" and are believed to help with infertility problems.
