Genesis 30:36 KJV

34And Laban said, Behold, I would it might be according to thy word.

35And he removed that day the he goats that were ringstraked and spotted, and all the she goats that were speckled and spotted, and every one that had some white in it, and all the brown among the sheep, and gave them into the hand of his sons.

36And he set three days’ journey betwixt himself and Jacob: and Jacob fed the rest of Laban’s flocks.

37And Jacob took him rods of green poplar, and of the hazel and chestnut tree; and pilled white strakes in them, and made the white appear which was in the rods.

38And he set the rods which he had pilled 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.
