Thematic Bible: Facts about breeding

And he removed that day the he goats that were ringstraked and spotted and all the she goats that were speckled and spotted and every one that had some white in it, and all the brown among the sheep and gave them into the hand of his sons. And he set three days' journey between himself and Jacob, and Jacob fed the rest of Laban's flocks. And Jacob took rods of green poplar and of the almond and chestnut tree and peeled white strakes in them and made the white appear which was in the rods. read more.
And he set the rods which he had peeled before the flocks in the gutters in the watering troughs when the flocks came to drink that they should conceive when they came to drink. And the flocks conceived before the rods and brought forth ringstraked, speckled, and spotted sheep. And Jacob separated the lambs, and put with his flock the ringstraked and all the brown in the flock of Laban; and he put his own flocks by themselves and did not put them together with Laban's sheep. And it came to pass, whenever the stronger sheep conceived, that Jacob laid the rods before the eyes of the sheep in the gutters that they might conceive among the rods. But when the sheep were feeble, he did not put them in; so the feebler were Laban's, and the stronger Jacob's. And the man increased exceedingly, and had many sheep, and maidslaves and menslaves, and camels, and asses.

If he said thus, The speckled shall be thy wages; then all the sheep bore speckled; and if he said thus, The ringstraked shall be thy hire; then all the sheep bore ringstraked. Thus God has taken away the livestock of your father and given them to me.
