1 Now when Rachel saw that she bore Jacob no children, she became jealous of her sister; and she said to Jacob, “Give me children, or else I die.” 2 Then Jacob’s anger burned against Rachel, and he said, “Am I in the place of God, who has withheld from you the fruit of the womb?” 3 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.” 4 So she gave him her maid Bilhah as a wife, and Jacob went in to her. 5 Bilhah conceived and bore Jacob a son. 6 Then Rachel said, “God has vindicated me, and has indeed heard my voice and has given me a son.” Therefore she named him Dan. 7Rachel’s maid Bilhah conceived again and bore Jacob a second son. 8 So Rachel said, “With mighty wrestlings I have wrestled with my sister, and I have indeed prevailed.” And she named him Naphtali.
9 When Leah saw that she had stopped bearing, she took her maid Zilpah and gave her to Jacob as a wife. 10Leah’s maid Zilpah bore Jacob a son. 11 Then Leah said, “How fortunate!” So she named him Gad. 12 Leah’s maid Zilpah bore Jacob a second son. 13 Then Leah said, “Happy am I! For women will call me happy.” So she named him Asher.
For three generations, the chosen of God have had barren wives. All of them try to make things happen themselves, instead of asking God for help. In this case, Jacob also has a wife who is not barren, and his two wives are sisters. It must have been a complicated mess for Jacob to wade through every day. His favorite wife was barren, the wife that had been forced upon him had born him four sons, and then both gave him their maidservants to bear children as well. What a load of contention they caused in the process. If we trust God, instead of trying to force things to work out for us, things will indeed work out much better in the end.
