Genesis 30:31-34

31Laban asked, “What should I give you?” And Jacob said, “You don’t need to give me anything. If you do this one thing for me, I will continue to shepherd and keep your flock.

32Let me go through all your sheep today and remove every sheep that is speckled or spotted, every dark-colored sheep among the lambs, and the spotted and speckled among the female goats. Such will be my wages.

33In the future when you come to check on my wages, my honesty will testify for me. If I have any female goats that are not speckled or spotted, or any lambs that are not black, they will be considered stolen.”

34“Good,” said Laban. “Let it be as you have said.”
