Genesis 30:37–43

Then Jacob took fresh sticks of poplar and almond and plane trees, and peeled white streaks in them, exposing the white of the sticks. He set the sticks that he had peeled in front of the flocks in the troughs, that is, the watering places, where the flocks came to drink. And since they bred when they came to drink, the flocks bred in front of the sticks and so the flocks brought forth striped, speckled, and spotted. And Jacob separated the lambs and set the faces of the flocks toward the striped and all the black in the flock of Laban. He put his own droves apart and did not put them with Laban’s flock. Whenever the stronger of the flock were breeding, Jacob would lay the sticks in the troughs before the eyes of the flock, that they might breed among the sticks, but for the feebler of the flock he would not lay them there. So the feebler would be Laban’s, and the stronger Jacob’s. Thus the man increased greatly and had large flocks, female servants and male servants, and camels and donkeys.

Jacob, however, took fresh-cut branches from poplar, almond and plane trees and made white stripes on them by peeling the bark and exposing the white inner wood of the branches. 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, they mated in front of the branches. And they bore young that were streaked or speckled or spotted. 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. 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, 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. In this way the man grew exceedingly prosperous and came to own large flocks, and female and male servants, and camels and donkeys.

Jacob then took branches of fresh poplar, almond, and plane wood, and peeled the bark, exposing white stripes on the branches. 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. The flocks bred in front of the branches and bore streaked, speckled, and spotted young. Jacob separated the lambs and made the flocks face the streaked sheep 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.

Whenever the stronger of the flock were breeding, Jacob placed the branches in the troughs, in full view of the flocks, and they would breed in front of the branches. As for the weaklings of the flocks, he did not put out the branches. So it turned out that the weak sheep belonged to Laban and the stronger ones to Jacob. And the man became very rich. He had many flocks, female and male slaves, and camels and donkeys.

Then Jacob took some fresh branches from poplar, almond, and plane trees and peeled off strips of bark, making white streaks on them. Then he placed these peeled branches in the watering troughs where the flocks came to drink, for that was where they mated. And when they mated in front of the white-streaked branches, they gave birth to young that were streaked, speckled, and spotted. Jacob separated those lambs from Laban’s flock. And at mating time he turned the flock to face Laban’s animals that were streaked or black. This is how he built his own flock instead of increasing Laban’s.

Whenever the stronger females were ready to mate, Jacob would place the peeled branches in the watering troughs in front of them. Then they would mate in front of the branches. But he didn’t do this with the weaker ones, so the weaker lambs belonged to Laban, and the stronger ones were Jacob’s. As a result, Jacob became very wealthy, with large flocks of sheep and goats, female and male servants, and many camels and donkeys.

Then Jacob took fresh branches of poplar, almond, and plane trees and peeled white strips on them, exposing the white which was on the branches. And he set the branches that he had peeled in front of the flocks, in the troughs that were in the water containers, where the flocks came to drink. And they were in heat when they came to drink. And the flocks mated by the branches, so the flocks bore streaked, speckled, and spotted. And Jacob separated the lambs and turned the faces of the flocks toward the streaked and all the dark-colored in Laban’s flocks. And he put his own herds apart, and did not put them with the flocks of Laban. And whenever any of the stronger of the flocks were in heat, Jacob put the branches in full view of the flock in the troughs that they might mate among the branches. But with the more feeble of the flock he would not put them there. So the feebler were Laban’s and the stronger were Jacob’s. And the man became exceedingly rich and had large flocks, female slaves, male slaves, camels, and donkeys.

And Jacob took him rods of green poplar, and of the hazel and chesnut tree; and pilled white strakes in them, and made the white appear which was in the rods. And he set the rods which he had pilled before the flocks in the gutters in the watering troughs when the flocks came to drink, that they should conceive when they came to drink. And the flocks conceived before the rods, and brought forth cattle ringstraked, speckled, and spotted. And Jacob did separate the lambs, and set the faces of the flocks toward the ringstraked, and all the brown in the flock of Laban; and he put his own flocks by themselves, and put them not unto Laban’s cattle. And it came to pass, whensoever the stronger cattle did conceive, that Jacob laid the rods before the eyes of the cattle in the gutters, that they might conceive among the rods. But when the cattle were feeble, he put them not in: so the feebler were Laban’s, and the stronger Jacob’s. And the man increased exceedingly, and had much cattle, and maidservants, and menservants, and camels, and asses.
