Genesis 30:39-41

Revised Geneva Translation

³⁹ And the sheep were in heat before the rods; and they brought forth young of parti-color and with small and great spots.

⁴⁰ And Jacob parted these lambs and turned the faces of the flock toward the parti-colored and all manner of black among the sheep of Laban. So, he put his own flock by themselves, and did not put them with Laban’s flock.

⁴¹ And in every ramming time of the stronger sheep, Jacob laid the rods before the eyes of the sheep in the gutters, so that they might conceive before the rods.
