Genesis 31:6-8, 41

You both know that I have worked as hard as I could for your father, but he cheated me and changed my pay ten times. But God has not allowed your father to harm me. When Laban said, ‘You can have all the speckled animals as your pay,’ all the animals gave birth to speckled young ones. But when he said, ‘You can have all the streaked animals as your pay,’ all the flocks gave birth to streaked babies.

I worked like a slave for you for twenty years—the first fourteen to get your two daughters and the last six to earn your flocks. During that time you changed my pay ten times.
