Genesis 30:37-39

Revised Geneva Translation

³⁷ Then Jacob took rods of green poplar, and of hazel, and of the chestnut tree, and peeled white strips in them, and made the white appear in the rods.

³⁸ Then he put the rods which he had peeled in the gutters and watering troughs where the sheep came to drink, so they could conceive (for they were in heat, when they came to drink).

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