Genesis 30:35-43

35And he removed that day the male goats that were striped and spotted, and all the female goats that were speckled and spotted, every one that had some white in it, and all the brown among the sheep, and gave them into the hands of his sons. 36And he set three days’ journey between himself and Jacob: and Jacob fed the rest of Laban’s flocks.

37And Jacob took to him rods of green poplar, and of the hazel and chesnut tree; and peeled white stripes in them, and made the white appear which was in the rods. 38And he set the rods which he had peeled before the flocks in the gutters in the watering troughs when the flocks came to drink, that they should conceive when they came to drink. 39And the flocks conceived before the rods, and brought forth cattle striped, speckled, and spotted. 40And Jacob separated the lambs, and set the faces of the flocks toward the striped, and all the brown in the flock of Laban; and he put his own flocks by themselves, and put them not with Laban’s cattle. 41And it came to pass, whenever the stronger cattle conceived, that Jacob laid the rods before the eyes of the cattle in the gutters, that they might conceive among the rods. 42But when the cattle were feeble, he put them not in: so the feebler were Laban’s, and the stronger Jacob’s. 43And the man increased exceedingly, and had many cattle, and female and male servants, and camels, and donkeys.
