Genesis 30:41 WBT

³⁹  And the flocks conceived before the rods, and brought forth cattle ring-streaked, speckled, and spotted.

⁴⁰  And Jacob separated the lambs, and set the faces of the flocks towards the ring-streaked, and all the brown in the flock of Laban: and he put his own flocks by themselves, and put them not with Laban's cattle.

⁴¹  And it came to pass, whenever the stronger cattle conceived, that Jacob laid the rods before the eyes of the cattle in the gutters, that they might conceive among the rods.

⁴²  But when the cattle were feeble, he put [them] not in: so the feebler were Laban's, and the stronger Jacob's.

⁴³  And the man increased exceedingly, and had many cattle, and maid-servants, and men-servants, and camels, and asses.
