Genesis 30:39-41

The Voice

³⁹ the flocks mated in front of the branches and produced young that were striped, speckled, and spotted. ⁴⁰ Jacob separated these newly born lambs from Laban’s flock, and when they mated again he faced Laban’s animals toward the striped and black animals. He kept his own droves separate from Laban’s. This is how he increased his own flock. ⁴¹ Whenever the stronger females of the flock were ready to mate, Jacob laid the striped branches in the troughs right in front of them, so that they would breed among them.
