Thematic Bible: Facts about breeding

and he turneth aside during that day the ring-streaked and the spotted he-goats, and all the speckled and the spotted she-goats, every one that hath white in it, and every brown one among the lambs, and he giveth into the hand of his sons, and setteth a journey of three days between himself and Jacob; and Jacob is feeding the rest of the flock of Laban. And Jacob taketh to himself a rod of fresh poplar, and of the hazel and chesnut, and doth peel in them white peelings, making bare the white that is on the rods, read more.
and setteth up the rods which he hath peeled in the gutters in the watering troughs (when the flock cometh in to drink), over-against the flock, that they may conceive in their coming in to drink; and the flocks conceive at the rods, and the flock beareth ring-streaked, speckled, and spotted ones. And the lambs hath Jacob parted, and he putteth the face of the flock towards the ring-streaked, also all the brown in the flock of Laban, and he setteth his own droves by themselves, and hath not set them near Laban's flock. And it hath come to pass whenever the strong ones of the flock conceive, that Jacob set the rods before the eyes of the flock in the gutters, to cause them to conceive by the rods, and when the flock is feeble, he doth not set them; and the feeble ones have been Laban's, and the strong ones Jacob's. And the man increaseth very exceedingly, and hath many flocks, and maid-servants, and men-servants, and camels, and asses.

'If he say thus: The speckled are thy hire, then bare all the flock speckled ones; and if he say thus: The ring-streaked are thy hire, then bare all the flock ring-streaked; and God taketh away the substance of your father, and doth give to me.
