Genesis 30:32-35

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.”

35That day Laban removed the streaked and spotted male goats and all the speckled and spotted female goats — every one that had any white on it — and every dark-colored one among the lambs, and he placed his sons in charge of them.
