Genesis 30:40-42

New Century Version

⁴⁰ Jacob separated the young animals from the others, and he made them face the streaked and dark animals in Laban’s flock. Jacob kept his animals separate from Laban’s. ⁴¹ When the stronger animals in the flock were mating, Jacob put the branches before their eyes so they would mate near the branches. ⁴² But when the weaker animals mated, Jacob did not put the branches there. So the animals born from the weaker animals were Laban’s, and those born from the stronger animals were Jacob’s.
