Rachel and Leah were the daughters of Laban. Rachel was more beautiful than Leah. This was the beginning of Rachel's problems. Rachel and Jacob were very much in love but the deception of Rachel's father had hurt her badly. It produced hurt and bitterness in her heart that she never really overcame.
Bitterness is like poison to the soul.
It destroys a person. Women of God need to be careful of the hurts and emotional wounds that may follow them from their backgrounds and childhood. These need to be dealt with. Only Jesus can heal these kinds of aliments. Rachel rightly thought that she had been exploited and sold.
