Genesis 31:4-9

So Jacob called Rachel and Leah out to the field where he was watching his flock. He said to them, “I have noticed that your father’s attitude toward me has changed. But the God of my father has been with me. You know how hard I have worked for your father, but he has cheated me, changing my wages ten times. But God has not allowed him to do me any harm. For if he said, ‘The speckled animals will be your wages,’ the whole flock began to produce speckled young. And when he changed his mind and said, ‘The striped animals will be your wages,’ then the whole flock produced striped young. In this way, God has taken your father’s animals and given them to me.
