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.
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,
Jacob separated the rams from the flock and made the rest of the sheep face any that were striped or black in Laban’s flocks. So he made separate herds for himself and did not add them to Laban’s flocks.
