Genesis 30:37-40

Living Bible

³⁷ Then Jacob took fresh shoots from poplar, almond, and sycamore trees, and peeled white streaks in them, ³⁸ and placed these rods beside the watering troughs so that Laban’s flocks would see them when they came to drink; for that is when they mated. ^39-40 So the flocks mated before the white-streaked rods, and their offspring were streaked and spotted, and Jacob added them to his flock. Then he divided out the ewes from Laban’s flock and segregated them from the rams, and let them mate only with Jacob’s black rams. Thus he built his flocks from Laban’s.
