Genesis 30:40-42

Christian Standard Bible

⁴⁰ 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.

⁴¹ 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. ⁴² 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.
