Genesis 30:40-42

Amplified Bible, Classic Edition

⁴⁰ Jacob separated the lambs, and [as he had done with the peeled rods] he also set the faces of the flocks toward the streaked and all the dark in the [new] flock of Laban; and he put his own droves by themselves and did not let them breed with Laban’s flock.

⁴¹ And whenever the stronger animals were breeding, Jacob laid the rods in the watering troughs before the eyes of the flock, that they might breed and conceive among the rods.

⁴² But when the sheep and goats were feeble, he omitted putting the rods there; so the feebler animals were Laban’s and the stronger Jacob’s.
