Genesis 30:31

28 Say then what your payment is to be and I will give it.

29 Then Jacob said, You have seen what I have done for you, and how your cattle have done well under my care.

30 For before I came you had little, and it has been greatly increased; and the Lord has given you a blessing in everything I have done; but when am I to do something for my family?

31 And Laban said, What am I to give you? And Jacob said, Do not give me anything; but I will again take up the care of your flock if you will only do this for me:

32 Let me go through all your flock today, taking out from among them all the sheep which are marked or coloured or black, and all the marked or coloured goats: these will be my payment.

33 And so you will be able to put my honour to the test in time to come; if you see among my flocks any goats which are not marked or coloured, or any sheep which is not black, you may take me for a thief.

34 And Laban said, Let it be as you say.
