And the sheep shall conceive at the rods, and shall bring forth sheep banded and speckled and patched. And Jacob separated the lambs, and he will give the faces of the sheep to the banded and every one black among the sheep of Laban: and he will set to himself the flocks, to himself alone, and not put them with Laban's sheep. And it was in every one conceiving of the strong sheep, and Jacob put the rods before the eyes of the sheep in the floorings, to conceive among the rods. And in the sheep being feeble, he will not put in: and those being feeble, were to Laban, and those being strong, to Jacob. And the man will break forth greatly, greatly; and there will be to him many sheep and maids, and servants, and camels and asses.
