Genesis 30

Not everything has to be a competition. Sometimes compromises bring out the best outcome. Leah and Rachel didn't have to compete. It led to bitter feelings and jealousy, sins of the world that wrecks our relationship with God. Jacob and Laban didn't have to try and manipulate one another with their flocks if only Laban wasn't so selfish. Jacob uses apparently tricky moves in order to help the deal move more towards his favour. God doesn't bless people who succumb to such actions. Such sin causes havoc in relationships.
