Genesis 31:6-9

You know that I’ve worked for your father with all my strength, yet your father has cheated me by changing my wages ten times. However, God has not allowed him to harm me. If he said, ‘The speckled ones will be your wages,’ then all the flocks gave birth to speckled young; and if he said, ‘The streaked ones will be your wages,’ then all the flocks bore streaked young. So God has taken away your father’s livestock and has given them to me.
