Psalms 129:6 - Exposition

Let them be as the grass upon the housetops ; literally, they shall be as the grass of housetops . The flat roofs of Oriental houses are usually covered in early spring with a crop of bright-green grass. But the scorching rays of the sun soon burn this up, and it becomes dry and withered. Which withereth afore it groweth up ; literally, before it is unsheathed ; i . e . before the blossom has left the sheath in which it is formed.
