38. Then he placed the peeled branches in all the watering troughs, so that they would be directly in front of the flocks when they came to drink. When the flocks were in heat and came to drink,
39. they mated in front of the branches. And they bore young that were streaked or speckled or spotted.
40. Jacob set apart the young of the flock by themselves, but made the rest face the streaked and dark-colored animals that belonged to Laban. Thus he made separate flocks for himself and did not put them with Laban’s animals.
41. Whenever the stronger females were in heat, Jacob would place the branches in the troughs in front of the animals so they would mate near the branches,
42. but if the animals were weak, he would not place them there. So the weak animals went to Laban and the strong ones to Jacob.
