Genesis 30:39-41

Good News Translation

³⁹ So when the goats bred in front of the branches, they produced young that were streaked, speckled, and spotted.

⁴⁰ Jacob kept the sheep separate from the goats and made them face in the direction of the streaked and black animals of Laban's flock. In this way he built up his own flock and kept it apart from Laban's.

⁴¹ When the healthy animals were mating, Jacob put the branches in front of them at the drinking troughs, so that they would breed among the branches.
