Parallel
Genesis 30:41
World English Bible British Edition · Berean Standard Bible
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 amongst the rods;
Whenever the stronger females of the flock were in heat, Jacob would place the branches in the troughs, in full view of the animals, so that they would breed in front of the branches.
