Jacob's family had a lot of family problems. He had major wife problems with all the fighting that went on between his wives, Leah and Rachel. Jacob loved Rachel more than Leah. When one was loved more than the other, there were always problems. In Genesis 29 it speaks about this.
At this point in Jacob's life, I feel that Jacob was very carnal in his thinking. I think a big part of why Jacob loved Rachel more than Leah was because of how she looked. She was well favored. She was probably a very pretty girl with a very good shape. That's what “well favored” means.
