To have stripped off skin or bark.

And Jacob took him rods of green poplar, and of the hazel and chestnut tree; and PILLED white streaks in them, and made the white appear which was in the rods. 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. ( Genesis 30:37-38 )
