Genesis 29

Laban was always looking for a deal. He sold his sister to a rich man. Now it turns out that he was willing  to give both his daughters away to get control of an heir. In short, he was what Jacob would have been had God not stepped in.

Jacob was a liar; Laban was a better liar. Jacob cheated people; Laban was better at that, too. Jacob had always lived by his wits; Laban was smarter, or at least more experierienced. The main difference between the two was that God had big plans for Jaco, he was contending to let Laban be Labn,

Ironically, being around someone worse made Jacob better.
