Genesis 30:41-43

New Revised Standard Version, Anglicised

⁴¹ Whenever the stronger of the flock were breeding, Jacob laid the rods in the troughs before the eyes of the flock, that they might breed among the rods, ⁴² but for the feebler of the flock he did not lay them there; so the feebler were Laban’s, and the stronger Jacob’s. ⁴³ Thus the man grew exceedingly rich, and had large flocks, and male and female slaves, and camels and donkeys.
