Genesis 30:40-42

English Standard Version

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, ⁴² but for the feebler of the flock he would not lay them there. So the feebler would be Laban's, and the stronger Jacob's.
