Genesis 30:37-39

New Living Translation

³⁷ Then Jacob took some fresh branches from poplar, almond, and plane trees and peeled off strips of bark, making white streaks on them. ³⁸ Then he placed these peeled branches in the watering troughs where the flocks came to drink, for that was where they mated. ³⁹ And when they mated in front of the white-streaked branches, they gave birth to young that were streaked, speckled, and spotted.
