Genesis 30:34-37

Laban said, “Good! Let it be as you have said.” But that day Laban removed the male goats that were striped and spotted, and all the female goats that were speckled and spotted, every one that had white on it, and every lamb that was black, and put them in the charge of his sons. And he set a distance of three days’ journey between himself and Jacob, and Jacob pastured the rest of Laban’s flock. Then Jacob took fresh sticks of poplar and almond and plane trees, and peeled white streaks in them, exposing the white of the sticks.
