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.
