Genesis 30:40-42

New Revised Standard Version Catholic Edition

⁴⁰ Jacob separated the lambs, and set the faces of the flocks toward the striped and the completely black animals in the flock of Laban; and 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 laid the rods in the troughs before the eyes of the flock, that they might breed among the rods, ⁴² but for the feebler of the flock he did not lay them there; so the feebler were Laban’s, and the stronger Jacob’s.
