Bereshis 30:40-42

Orthodox Jewish Bible

⁴⁰ And Ya’akov did separate the kesavim, and set the faces of the tzon toward the streaked, and all the dark in the tzon Lavan; and he put his own adarim (flocks) by themselves, and put them not unto the tzon Lavan.

⁴¹ And it came to pass, whensoever tzon hamekusharot (the stronger flock) did breed, that Ya’akov set the maklot before the eyes of the tzon in the trough channels, that they might breed among the maklot.

⁴² But when the tzon were feeble, he put them not in: so the feebler would belong to Lavan, and the stronger to Ya’akov.
