Genesis 30:40-42

New Catholic Bible

⁴⁰ As for the sheep, Jacob separated them and had them face the animals that were streaked or fully dark of the flock of Laban. He put his own flock in a separate place; he did not put them together with Laban’s flock. ⁴¹ Every once in a while, the healthier animals mated, and Jacob would put the shoots in the trough where the animals could see them, so that they would mate in the sight of the shoots. ⁴² When the animals were weak, he did not put them there. Thus, the weak animals belonged to Laban, and those that were healthy belonged to Jacob.
