Genesis 30:31-33

“So, what should I pay you?” Jacob said, “You don’t have to pay me a thing. But how about this? I will go back to pasture and care for your flocks. Go through your entire flock today and take out every speckled or spotted sheep, every dark-colored lamb, every spotted or speckled goat. They will be my wages. That way you can check on my honesty when you assess my wages. If you find any goat that’s not speckled or spotted or a sheep that’s not black, you will know that I stole it.”
