Psalms 129:6-7

⁶Be they made as the hay of housetops; that dried up, before that it be drawn up. (Be they made like the grass on the rooftops; it dried up, before that it could be pulled up.)

⁷Of which hay he that shall reap, shall not fill his hand; and he that shall gather handfuls, shall not fill his bosom. (Of which grass he who shall reap, shall not get a handful; and he who shall gather handfuls, shall not get an armful.)
