Genesis 30:38

38 He set the peeled branches in the troughs in front of the sheep-in the water channels where the sheep came to drink. And the sheep bred when they came to drink.

Genesis 30:38 In-Context

36 He put a three-day journey between himself and Jacob. Jacob, meanwhile, was shepherding the rest of Laban's flock.
37 Jacob then took branches of fresh poplar, almond, and plane wood, and peeled [the bark], exposing white stripes on the branches.
38 He set the peeled branches in the troughs in front of the sheep-in the water channels where the sheep came to drink. And the sheep bred when they came to drink.
39 The flocks bred in front of the branches and bore streaked, speckled, and spotted young.
40 Jacob separated the lambs and made the flocks face the streaked and the completely dark sheep in Laban's flocks. Then he set his own stock apart and didn't put them with Laban's sheep.
