Genesis 30:9

When Leah saw that she had stopped having children, she gave her servant Zilpah to Jacob as a wife, even though she already had four sons.

• The rivalry between these sisters explains much of the later conflict among their sons, and then among the tribes. This is similar to how Jacob and Laban's rivalry predicted future conflicts between Israel and the Arameans of Damascus (2 Samuel 8:5–6; 10:8–19; 1 Kings 20:1–34; 2 Kings 5:1–8:29; 13:1–25; Isaiah 7:1–9).

• God fights for the cause of the poor and oppressed. He honored Leah, the despised first wife, by making her the first mother. Judah's royal tribe and Levi's priestly line came from her. This was despite Jacob's favoritism for Rachel and her children.

  Despite the tension and jealousy resulting from Laban’s deceit and Jacob’s favoritism, God still grew Jacob’s family and brought about the births of the tribal ancestors.

• These chapters describe how God fulfilled his promise by greatly blessing Jacob with a family and possessions. God also disciplined Jacob, leaving him to struggle with Laban for many years. Laban was Jacob’s match in deception, and thus a means of correction.

• The story of Jacob and Laban is similar to Israel's later stay in Egypt. Jacob struggled while serving his uncle but finally emerged with a large family (the founders of the 12 tribes) and great wealth. In Egypt, the Israelites suffered under their oppressors, but they also flourished, becoming a great nation of 12 large tribes and escaping with great riches.
