Génesis 30

Whenever the stronger of the flock conceived, Jacob laid the rods in front of the eyes of the flock in the watering troughs, that they might conceive among the rods;

Y sucedía que cuantas veces se recalentaban las tempranas, Jacob ponía las varas delante de las ovejas en las pilas, para que concibiesen á la vista de las varas.

And it came to pass, whensoever the stronger cattle did conceive, that Jacob laid the rods before the eyes of the cattle in the gutters, that they might conceive among the rods.
