Genesis 30:39-41

English Standard Version

³⁹ the flocks bred in front of the sticks and so the flocks brought forth striped, speckled, and spotted. ⁴⁰ And Jacob separated the lambs and set the faces of the flocks toward the striped and all the black in the flock of Laban. He put his own droves apart and did not put them with Laban's flock. ⁴¹ Whenever the stronger of the flock were breeding, Jacob would lay the sticks in the troughs before the eyes of the flock, that they might breed among the sticks,
