The measurement of terumah: Beit Shammai say, one with a good eye (i.e., a generous person) gives one in thirty, the average person gives one in forty, and the wicked person gives one in fifty. Beit Hillel say, one with a good eye gives one in forty, the average person gives one in fifty, and the wicked person gives one in sixty. (See Ter. 4:3.)
