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.
Berean Study Bible (BSB) - Genesis 30:41 >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.
