Genesis 30:34-37

“Agreed!” Laban said. “We’ll do what you’ve suggested.” But that same day, Laban secretly removed all the male and female goats that were speckled or spotted (all that had white on them) and all the black lambs and left them under the care of his sons. He set a distance of a three-day journey between himself and Jacob, while Jacob continued to tend the rest of Laban’s flocks. Jacob, however, cut green branches of poplar, almond, and plane trees and peeled back part of their bark, to expose the white inner wood of the branches.
