When the boughs thereof are withered, they shall be broken off: the women come, and set them on fire: for it is a people of no understanding: therefore he that made them will not have mercy on them, and he that formed them will shew them no favour.
When the branches dry up, they get removed; women then light them on fire because this people don't understand. Since the creator won't show them mercy and the maker won't favor them, it's a harsh outcome for those who don't comprehend.
