Genesis 30:37-39

International Standard Version

³⁷ Jacob took branches^[a] from white poplar trees, freshly cut almond trees, and some other trees,^[b] stripped off their bark to make white streaks, and uncovered the white part inside the branches. ³⁸ Then he placed the branches that he had stripped bare in all the watering troughs where the flocks came to drink. He placed the branches in front of the flock, and they went into heat as they came to drink. ³⁹ When the flocks mated in front of the branches, they would bear offspring^[c] that were striped, speckled, or spotted.
