有比丘得乾痟病，糞掃臥具重，不堪持行，佛言：從僧三乞更作新者，當白二與之也。

There was a bhikṣu who contracted a wasting-thirst disease; his rags-and-scraps rug was heavy, and he was incapable of carrying it on the move. The Buddha said: he should request three times from the saṃgha to make a new one, and it should be granted to him by a jñaptidvitīyā-karman.
