Genesis 30:35-43

35So he removed on that day the striped or spotted male goats, and all the speckled or spotted female goats, every one with white on it, and all the black ones among the sheep, and put them in the 1care of his sons. 36And he put a distance of three days’ journey between himself and Jacob, and Jacob fed the rest of Laban’s flocks.

37Then Jacob 2took fresh rods of poplar, almond, and plane trees, and peeled white stripes in them, exposing the white that was 3in the rods. 38He set the rods which he had peeled in front of the flocks in the drinking troughs, that is, in the watering channels where the flocks came to drink; and they mated when they came to drink. 39So the flocks mated by the rods, and the flocks delivered striped, speckled, and spotted offspring. 40Then Jacob separated the lambs, and 4made the flocks face toward the striped and all the black in the flock of Laban; and he put his own herds apart, and did not put them with Laban’s flock. 41Moreover, whenever the stronger of the flock were mating, Jacob would place the rods in the sight of the flock in the drinking troughs, so that they would mate by the rods; 42but when the flock was sickly, he did not put them in; so the sickly were Laban’s, and the stronger were Jacob’s. 43So 5the man 6became exceedingly prosperous, and had large flocks, and female and male servants, and camels and donkeys.
