Genesis 30:31-34

31And he said, What shall I give thee? And Jacob said, Thou shalt not give me anything. If thou doest this for me, I will again feed [and] keep thy flock:

32I will pass through all thy flock to-day, to remove thence all the speckled and spotted sheep, and all the brown lambs, and the spotted and speckled among the goats; and [that] shall be my hire.

33And my righteousness shall answer for me hereafter, when thou comest about my hire, before thy face: all that is not speckled and spotted among the goats, and brown among the lambs, let that be stolen with me.

34And Laban said, Well, let it be according to thy word.
