Genesis 31:7-8

31:7 but your father has humiliated me and changed my wages ten times. But God has not permitted him to do me any harm. 31:8 If he said, ‘The speckled animals will be your wage,’ then the entire flock gave birth to speckled offspring. But if he said, ‘The streaked animals will be your wage,’ then the entire flock gave birth to streaked offspring.

Genesis 31:41

31:41 This was my lot for twenty years in your house: I worked like a slave for you – fourteen years for your two daughters and six years for your flocks, but you changed my wages ten times!
