Genesis 30:29-34

29Jacob said to him, “You know how I have worked for you and how your livestock has fared under my care.

30The little you had before I came has increased greatly, and the LORD has blessed you wherever I have been. But now, when may I do something for my own household?”

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.”
