To Know God is to Know His Word

Genesis 30:37 ¶ And Jacob took him rods of green poplar, and of the hazel and chesnut tree; and pilled white strakes in them, and made the white appear which was in the rods.

38 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.

39 And the flocks conceived before the rods, and brought forth cattle ringstraked, speckled, and spotted.
