Genesis 30:31-34

31He said, "What shall I give you?" Jacob said, "You shall not give me anything. If you will do this for me, I will again pasture your flock and keep it:

32let me pass through all your flock today, removing from it every speckled and spotted sheep and every black lamb, and the spotted and speckled among the goats, and they shall be my wages.

33So my honesty will answer for me later, when you come to look into my wages with you. Every one that is not speckled and spotted among the goats and black among the lambs, if found with me, shall be counted stolen."

34Laban said, "Good! Let it be as you have said."
