Genesis 30:41-43

The Voice

⁴¹ Whenever the stronger females of the flock were ready to mate, Jacob laid the striped branches in the troughs right in front of them, so that they would breed among them. ⁴² But when he saw the feebler animals ready to mate, he didn’t lay the rods out so that in the end, the feebler of the animals became Laban’s and the stronger became Jacob’s. ⁴³ In this way, Jacob grew extremely rich, and he ended up with very large flocks, male and female slaves, and camels and donkeys too.
