Genesis 30:38-40

Good News Translation

³⁸ He placed these branches in front of the flocks at their drinking troughs. He put them there, because the animals mated when they came to drink. 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.
