He placed the peeled branches in the troughs directly in front of the flocks, at the watering places where the flocks came to drink. When they were in heat and came to drink,
Then Jacob took fresh-cut branches of poplar, almond, and plane trees and peeled the bark on them in strips of white, uncovering the white which was on the branches.
Whenever the stronger of the flocks were in heat, Jacob would lay the branches in the troughs in front of them so that they would mate by the branches.
