Genesis 30:35-43

35On that day he removed the colorfully striped and colorful billy goats as well as all the colorfully spotted goats—everyone with white on it—and every dark-colored one among the lambs, and he put them in the hand of his sons.

36Then he put a three-day’s journey between them and Jacob, while Jacob was shepherding Laban’s remaining flocks.

37But Jacob took fresh white poplar, almond, and plane tree branches, peeled away white stripped sections on them, exposing the white of the branches.

38Then he set the branches he had peeled in front of the flocks in the drinking troughs and watering channels where the flocks come to drink. Since they were in heat when they came to drink,

39the flocks mated near the branches, and the flocks gave birth to striped, spotted and colorful ones.

40Now Jacob separated the lambs and set the faces of the flocks toward the striped ones as well as all the dark-colored ones among Laban’s flocks. Then he set aside the herds for himself and did not put them with Laban’s flocks.

41Whenever the strong flocks mated, Jacob put the branches in the watering troughs before the eyes of the flocks, to have them mate near the branches.

42But when the flocks were sickly, he did not put the branches down—so the sickly ones became Laban’s and the stronger ones became Jacob’s.

43And the man grew exceedingly prosperous and had numerous flocks, along with female and male servants, camels and donkeys.
