Genesis 30:37-39

Douay-Rheims 1899 American Edition

³⁷ And Jacob took green rods of poplar, and of almond, and of plane trees, and pilled them in part: so when the bark was taken off, in the parts that were pilled, there appeared whiteness: but the parts that were whole remained green: and by this means the colour was divers.

³⁸ And he put them in the troughs, where the water was poured out: that when the flocks should come to drink, they might have the rods before their eyes, and in the sight of them might conceive.

³⁹ And it came to pass that in the very heat of coition, the sheep beheld the rods, and brought forth spotted, and of divers colours, and speckled.
