Genesis 31:6-9

You know that I have served your father with all my strength. Yet your father has cheated me [as often as possible] and changed my wages ten times; but God did not allow him to hurt me. If he said, ‘The speckled shall be your wages,’ then the entire flock gave birth to speckled [young]; and if he said, ‘The streaked shall be your wages,’ then the entire flock gave birth to streaked [young]. Thus God has taken away the flocks of your father and given them to me.
