Genesis 30:37 WBT

³⁵  And he removed that day the he-goats that were ring-streaked and spotted, and all the she-goats that were speckled and spotted; every one that had [some] white in it, and all the brown among the sheep, and gave [them] into the hands of his sons.

³⁶  And he set three days' journey between himself and Jacob: and Jacob fed the rest of Laban's flocks.

³⁷  And Jacob took to him rods of green poplar, and of the hazel and chesnut-tree; and peeled white streaks in them, and made the white appear which [was] in the rods.

³⁸  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.

³⁹  And the flocks conceived before the rods, and brought forth cattle ring-streaked, speckled, and spotted.
