Genesis 30:31-34

31“What shall I give you?” he asked. “Don’t give me anything,” Jacob replied. “But if you will do this one thing for me, I will go on tending your flocks and watching over them:

32Let me go through all your flocks today and remove from them every speckled or spotted sheep, every dark-colored lamb and every spotted or speckled goat. They will be my wages.

33And my honesty will testify for me in the future, whenever you check on the wages you have paid me. Any goat in my possession that is not speckled or spotted, or any lamb that is not dark-colored, will be considered stolen.”

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