Genesis 30:32-40

32Let me pass through your entire flock today, removing from it every speckled and spotted sheep and every dark or black one among the lambs and the spotted and speckled among the goats; and those shall be my wages.

33So my honesty will be evident for me later, when you come [for an accounting] concerning my wages. Every one that is not speckled and spotted among the goats and dark among the young lambs, if found with me, shall be considered stolen.”

34And Laban said, “Good! Let it be done as you say.”

35So on that same day Laban [secretly] removed the male goats that were streaked and spotted and all the female goats that were speckled and spotted, every one with white on it, and all the dark ones among the sheep, and put them in the care of his sons.

36And he put [a distance of] three days’ journey between himself and Jacob, and Jacob was then left in care of the rest of Laban’s flock.

37Then Jacob took branches of fresh poplar and almond and plane trees, and peeled white stripes in them, exposing the white in the branches.

38Then he set the branches which he had peeled in front of the flocks in the watering troughs, where the flocks came to drink; and they mated and conceived when they came to drink.

39So the flocks mated and conceived by the branches, and the flocks gave birth to streaked, speckled, and spotted offspring.

40Jacob separated the lambs, and [as he had done with the peeled branches] he made the flocks face toward the streaked and all the dark or black in the [new] flock of Laban; and he put his own herds apart by themselves and did not put them [where they could breed] with Laban’s flock.
