1 MOSEBOG 30:38

og de afskrællede Grene stillede han op i Trugene foran Dyrene, i Vandrenderne, hvor Dyrene kom hen og drak; og de parrede sig, når de kom for at drikke;

And he set the rods which he had pilled 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.
