Genesis 30:31-33

31And he said, What shall I give thee? And Jacob said, Thou shalt not give me aught: if thou wilt do this thing for me, I will again feed thy flock and keep it. 32I will pass through all thy flock to-day, removing from thence every speckled and spotted one, and every black one among the sheep, and the spotted and speckled among the goats: and of such shall be my hire. 33So shall my righteousness answer for me hereafter, when thou shalt come concerning my hire that is before thee: every one that is not speckled and spotted among the goats, and black among the sheep, that, if found with me, shall be counted stolen.
